Abstract

The double pipe heat exchanger (DPHE) is one type of heat exchanger (HE) that is commonly used in industrial applications such as electricity generation, petrochemical industry, process industry, and other industries. The double pipe heat exchangers are commonly used because of low design costs and maintenance costs. The need to achieve optimal double pipe heat exchanger performance, this research will examine the optimization of double pipe heat exchanger performance by varying fluid flow velocity and adding twisted tape insert with a twist ratio (H/D) = 6 in terms of Nusselt number (Nu), friction factor (f), and effectiveness (?). The test is carried out with fluid in the form of water and fluid flow velocity variations are 2.5, 3.5, 4.5, 5.5, and 6.5 LPM. The experimental results show that the Nusselt number value and effectiveness have increased with increasing fluid flow velocity. While the friction factor value decreases with increasing fluid flow velocity. The increase in Nusselt numbers was 2.14 times and the effectiveness value was 8.69%. While the value of the friction factor decreased by 55%. The optimum fluid flow velocity obtained from the results of the study is 6.5 LPM with Nusselt number, friction factor, and effectiveness reaching 48.43; 0.27; and 0.259.

Abstract

In the implementation of the siphon system it is used to prevent failure of rising groundwater levels that flow in the highlands including mountain slopes. The siphon system experiences greater drop pressure along with the increase in the height of the siphon, which should have higher pressure with a constant flow and an increase in the height of the siphon to achieve greater siphon system efficiency. To find out the value of pressure drop and the cause of the pressure drop on the siphon system, three methods are used, namely theoretical calculation, simulation of CFD ANSYS and actual measurements using pressure gauge water of bordoun type analogous with variations of valve opening 100% full opened, 66,67% opened, and 33,33% opened and the heights of the siphon are 1 meter, 1,5 meters and 2 meters. From the results of the three methods, the average water flow rate varies based on the height of siphon 1 meter, 1,5 meters and 2 meters is 0,0000854 m3/s to 0,0002716 m3/s and the average pressure of 111.736,7 N/m2 to 88.899,57 N/m2. While the average value of siphon based on variations in valve openings with the same height of siphon is obtained 83.939,634 N/m2 to 130.400,615 N/m2. In addition, an error value between theoretical calculation and CFD simulation of 0,03% to 1,18% and error of the between theoretical calculations and actual measurements is 0,08% to 1,10%.

Abstract

Heat Exchanger is a device used to transfer thermal energy between two or more fluids, or between solid surface and fluids, with different temperature. One of low capacity heat exchanger known in Industry is the double pipe heat exchanger. This heat exchanger usually consists of two concentric pipes with plain of finned inner pipe. Because of its low capacity, the performance of double pipe heat exchanger needs to be improved to achieve optimal operating condition. This research contains an experimental study of optimizing double pipe heat exchanger?s performance by varying the Reynolds number which is reviewed from the value of Nusselt number (Nu) and friction factor (f). The double pipe heat exchanger is tested with 2500, 3500, 4500, 5500, and 6500 Reynolds number value with 20?C of cold fluid flows through the inner pipe, and 40?C of hot fluid flows through the annulus pipe. The fluids flow with counterflow condition. Based from the experimental results, it is known that by the increasing of Reynolds number, the Nusselt number increased by 2.14 times, and the friction factor decreased by 1.13 times from Reynolds number of 2500 to Reynolds number of 6500. The optimal Reynolds number resulted in Reynolds number of 3900 with Nusselt number of 32.41 and friction factor of 0.0491.

Abstract

Piping network is one of the needs as a means of distributing water or other fluids in everyday life and industry. Water is used to produce steam in Power Plant to generate electricity. Selection of the right size, material and installation can help to reduce initial costs, maintenance costs and as a safety factor. Pipe bifurcation is a piping component needed in the installation so that the fluid can be split to several destinations. One of bifurcation of pipe is tee-junction. This study discusses the distribution of pressure at tee junction with experiments through measurements in the Branch Line System test module and numerical methods using the Computational Fluid Dynamics simulation of ANSYS. This research was conducted by varying the configuration of several branching using a constant mass flow entering the tee junction. The results obtained show that the pressure value at the tee junction inlet decreases at outlets 90? and 180? due to pressure loss. The highest loss of pressure is 5884 Pa in the branch flow and 4903 Pa in the line flow while the smallest loss is 2942 Pa for branch flow and 1961 Pa for line flow. Separation and recirculation flow is occured in the junction at the junction.

Abstract

In implementation, PLTMH utilizes different head heights so that the potential energy of water is converted into mechanical energy to turn turbines. Then the generator will convert mechanical energy from the turbine shaft rotation into electrical energy. In the operation of PLTMH, fluctuating loads cause unstable frequencies and voltages that can damage electrical equipment and cause overspeed generators when the load is very low. To regulate fluctuating loads on modern PLTMH using ELC (Electric Load Controller). The working principle of the ELC is to control the load which aims to balance the power generated by the generator with the power used by consumers. The results of the simulation conducted by a generator with 30 VA power require an excitation voltage of 52.2 V dc, the dc voltage of the buck converter is capable of producing an output of 52.2 V with a duty cycle value of 0.725%. Changes in consumer loads cause the value of the generator voltage to increase, namely loading from a scale of 11-30 KW with a voltage reading of 220-235 V line-neutral. The decrease in consumer load results in the power transferred to the ballast load being greater, namely alpha angle variation from 0o - 180o. A decrease in consumer load from a scale of 11-30 KW results in the power being transferred to ballast loads from 0 KW - 30 KW. ELC is able to maintain line-neutral voltage on the 220 V set point and has 100% accuracy. The ELC simulation results are able to maintain a 220 V set point voltage with a power capacity generated by a 30 VA generator.
