HYDRODYNAMICS AND HEAT TRANSFER IN INTRICATELY SHAPED CHANNELS OF POWER UNITS OF TRANSPORTATION SYSTEMS

The authors have presented the results of modeling of the processes of transfer of various working media in intricately shaped channels, including the case of fl ow-rate and pressure pulsations. An approach has been proposed to creating reliable computer models of a lubrication system and a gas-intake system for an in-line six-cylinder engine. Consideration has been given to the channels of lubrication, gas-exchange and cooling systems for diff erent operation regimes of transportation systems with allowance for the features of functioning of an oil pump, a turbocompressor, and a liquid pump. Based on the results of calculations with the reliable computer model, technical solutions have been proposed for changing the geometry of the channels to reduce the hydraulic loss in them and to equalize the distribution of mass fl ow rates in branching channels
