Abstract

Nowadays, the development of propeller design planning has developed quite rapidly. Series propellers on the market are not only B-Series, Kaplan Series, AU Series, Gwan Series and SK Series. Some series propellers have characteristics of propeller design. Now there are many new series of propeller on the market which is the result of a variety of propeller series that have been there before. With technological advances, software assistance can simulate a new series of propellers with a sufficiently short period of time to get the desired propeller performance results. This research discusses the performance of B-series propellers in open water with variation of rake angle from -3 °, -2 °, -1 °, 0 °, 5 °, 10 ° and 15 ° also variation of skew angle 12 ° and 22 ° using a computational fluid dynamic method (CFD) approach. The purpose of this research is to analyze propeller model to get the highest thrust propeller model, lowest torque, highest efficiency, highest static pressure and highest velocity.

Abstract

Livestock vessels are used to distribute and transport livestock from one place to another. Similar research has been carried out by making cattle models in the beams which are considered to make air distribution less evenly. This research will be carried out simulation use 3D cattle’s model. This simulation aims to determine the distribution of air temperature, air velocity, air pressure and air flow patterns uses a CFD (computational fluid dynamic) simulation method. Based on the simulation result, the average of air temperature distribution is 300oK or 27oC at cattle pen A and B. The average of air velocity distribution is 0,669 m/s at cattle pen A and 0,7 m/s at cattle pen B. The average of air pressure distribution is 0,211 pa at cattle pen A and -0,267 pa at cattle pen B and the airflow pattern is around a model of cattle. The distribution of air temperature at 300oK or 27oC by RH (relative humidity) 70%-90%, THI (Temperature Humidity Index) shows in the alert condition between 75 – 78. So, The cattle pen A and B have not good the comfort zone and make a cattle to be mild stress. Because of it, the air temperature has to be down by adding a cooling instrument.

Abstract

Savonius water turbines can work at low fluid flow rates and have high torque, but have disadvantageswhich is the lowest Cp value compared to other turbine types. Efficiency can be improved by changing the shapeof the Savonius Turbine blade using the myring equation and adding an obstacle. The experimental method in thisstudy combines two blades resulting from variations of the value (n) in the myring equation n = 1 and n = 2, withmyring n = 1 placed on the concave side and n = 2 on the convex side. To improve performance, a 12 cm diametercircular cylinder is placed in front of the advancing blade with varying stagger angles. The test model has a heightof 0.40 m and a diameter of 0.40 m which will be tested in a flowing tank with a width of 1 m and height of 1 m.Experiments were carried out at a current speed of 0.2 m / s by measuring the turbine rotation and load to producea torque coefficient and a power coefficient. The experimental results show that the placement of the circularcylinder with ds / D = 0.3, S / D = 0.75, and ? = 60º obtained the highest performance with an angular velocityof 0.5160 rad / s, Coefficient of torque (Ct) of 0.2936 and Coefficient of power (Cp) of 0.1515. With a percentageincrease compared to myring n = 1 and n = 2 without an obstacle of 10.27%, this proves that the addition of acircular cylinder can improve the performance of Savonius water turbines.

Abstract

Indonesia has a great potential to use water currents as an energy source that can be convertedinto electricity. Savonius water turbines can be used as its solution to make it. Its performance can be improvedby modifying its combined blades with myring n=1 and n=2 and also by adding a circular cylinder on it. TheComputational Fluid Dynamics (CFD) method with Ansys 17.2-Fluent and Tecplot software are chosen and usedfor its flow characteristics study produced by the turbine. Gambit software is also used to create geometry anddomain models. The boundary condition of the model include the inlet as the input properties area with an initialvelocity of 0.22 m/s as analysis limitation of control surface on the test model. The modification include the useof combined blade with myring n=1 and n=2. One circular cylinder is added in front of the advancing blade sothat the flow velocity will be higher and its efficiency can be increased. Circular cylindrical diameters are variousi.e. ds/D=0.2; 0.3 and 0.4 with 0?, 30? and 60? stagger elevation angles. The results obtained from this researchare the values of torque coefficient (Cm), power coefficient (Cp), pressure distribution and fluid flowcharacteristics. Turbine performance has the highest increase (35.86%) on ds/D =0.4 with 60? stagger elevationangle variation. The greatest decrease (30.11%) occured on ds/D=0.4 0? stagger elevation angle variation withoutusing circular cylinder.

Savonius water turbine has the opportunity to be developed. An innovation is needed toimprove the performance of savonius water turbines. An experimental study on the effect of installing acircular cylinder with varying diameters on the advancing blade side of the savonius water turbineperformance needs to be carried out. The experiment used savonius water turbine myring n = 1 andmyring n = 2 with a diameter and rotor height of 40 cm each. Circular cylinder diameter variations usedare ds/D=0.2, ds/D=0.3, and ds/D=0.4. Circular cylinder is positioned at a distance of X/D=0.5 andY/D=0.7. The result is the coefficient of torque (Ct) and the coefficient of power (Cp). In addition, thediameter of the circular cylinder that is capable of producing the best performance of Savonius waterturbines will be obtained.

Abstract

Turbin air savonius adalah jenis turbin sumbu vertikal yang mempunyai torsi awal yang tinggi dan dapat berputar pada kecepatan aliran fluida yang rendah, sehingga dapat diterapkan pada perairan di Indonesia. Turbin tersebut dapat digunakan pada aliran air untuk mengubah energi kinetik menjadi energi mekanik. Potensi tersebut akan dapat meningkatkan performa turbin. Penelitian ini akan menggunakan metode simulasi CFD (ComputationalFluid Diagram) dengan software Ansys Fluent dan mengkombinasikan dua sudu berbeda yang merupakan hasil variasi nilai (n) pada persamaan Myring n=1 dan n=2. Turbin yang akan disimulasikan memiliki ukuran tinggi 40 cm dan diameter 40 cm. Selain kecepatan arus yang digunakan sebesar 0,22 m/s. Di depan sisi returning blade, silinder sirkular dipasang sebagai pengganggu dengan variasi diameter 8 cm, 12cm, dan 16 cm yang berfungsi untuk meningkatkan performa turbin. Stagger divariasikan pada sudut 0º, 30?, 60º. Hasil yang diperoleh pada simulasi ini menunjukkan bahwa diameter stagger 16 cm dengan sudut 60? memiliki peningkatan performa tertinggi, yakni sebesar 19,9007%. Sedangkan variasi diameter stagger 16 cm dengan sudut 0? menurun sebesar 30,1087% dari turbin air savonius tanpa stagger.

Abstract

The coefficient of power Savonius wind turbine improved in experimental studies that added overlap and variation in the distance of the disruptive cylinder in front of the returning blade. However, further research needs to be done to validate the experimental results. This research is in the form of a numerical study using the 3-dimensional Computational Fluid Dynamics (CFD) method. In this simulation, the solver chosen is pressure based with a transient time mode. In addition, the model used is the k-epsilon realizable model. Simulations were carried out to determine the value of the coefficient of power the turbine. The turbine has the same diameter and height of 0.4 meters with the addition of overlap. The variation in the distance of the disruptive cylinder used is S/d = 1.4; S/d = 1.7; S/d = 2 and S/d = 2.3. The final result shows that the performance of the turbine can reach the highest increase of 3.51% compared with overlapped Savonius wind turbine without cylinder at a distance of S/d = 1.7. The coefficient of power (Cp) value is 0.324 at Tip Speed Ratio 1.
