Aerothermodynamically Re-Design of an Air-Cool Heat Exchanger Fin Configuration Utilized for Cooling the Lubricating Oil of a Gas Turbine Unit Benefiting from Numerical Simulation, M.Sc. Thesis Sharif University of Technology ; Darbandi, Masoud (Co-Advisor)
Abstract
The lubricating oil is commonly used to cool down the moving parts of turbine gas systems. In many applications, this oil is cooled down using a recirculating water circuit. The water is then cooled down using an air-cooled heat exchanger. Any deficiency in aerothermodynamic design of such heat exchanger would result in high temperature of gas turbine moving parts such as bearings. Obviously, this mal-performance has adverse effect on the lifetime of these parts and their maintanence aspects. Since the good performance of air-cooled heat exchanger has numerous advantages for the performance of related gas turbine unit, it is mandatory to design these heat exchangers in minimum sizes and...
