| Abstract:The cooling system flow and heat-transfer analysis model for test bench of a 150 single-cylinder engine was established by Flowmaster. The cooling water heat-transfer model was verified on a large power engine. The influences of coolant temperature, coolant flow, the temperature of cylinder liner and cover to total heat transfer flow are calculated and analyzed, as well as the influences of pipe size, surface roughness, coolant flow to total flow resistance. |
