Thermal-mechanical characteristics of stationary and pulsating gas-flows in a gas-dynamic system: In relation the exhaust system of an engine

It is a relevant objective in thermal physics and building reciprocating internal combustion engines (RICE) to obtain new information about the thermal-mechanical characteristics of both stationary pulsating gas-flows complex gas-dynamic system. The article discusses physical features gas dynamics heat transfer flows along length system typical for RICE exhaust systems. Both an experimental set-up techniques are described. An indirect method determining local coefficient pipe-lines with constant temperature hot-wire anemometer proposed. regularities changes instantaneous values flow rate time different elements obtained. change turbulence number systems established (it shown that gas-flow 1.3-2.1 times higher than flow). engine?s were identified was 1.05-1.4 Empirical equations obtained determine
