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

Gas and steam power plant (PLTGU) is a combined cycle between PLTG and PLTU. The parameters to be achieved in order for the PLTG system to work optimally are regulated in ISO 39772. The gas turbine can work optimally if the air temperature enters the compressor 15ᵒC, at 60% moisture and at a pressure of 101.3 kPa. But data from BMKG condition of environment in Gresik mean at temperature 32ᵒC at relative humidity 65% to 85%. Therefore a cooling system is required to cool the inlet air gas turbine. On the other hand the exhaust gas temperature from HRSG still high and can be utilized as the energy source of the absorption cooling system. From the results of balanced energy calculations obtained some results such as the amount of exhaust gases from HRSG of 52952 kW and the power required to cool the inlet air of 22365.65 kW. The result of exergy calculation obtained some results the biggest destroyed of energy in combustor amount of 287369 kW. Five absorption cooling machine LG type WC2N135 is arranged in parallel to achieved the power. When the turbine inlet temperature is 32°C the power is 125251,127 kW otherwise turbin inlet temperature is 15ᵒC the power is 139986,53 kW.
