Boundary Conditions for Numerical Calculation of Gas Exchange in Piston Engines

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

An estimation of the efficiency of the technique of setting boundary conditions with the use of gas-dynamical functions to numerically calculate the intake and exhaust processes in piston engines is made. Mathematical models have been developed for different engines, and joint calculations of nonstationary gas flow and of the process proceeding in the cylinder have been carried out. A comparison of the obtained results with experimental data has been made, and the adequacy of the mathematical description has been confirmed.
