Numerical Simulation of Intrachamber Processes in the Power Plant

This paper considers the issues of numerical modeling nonstationary spatial gas dynamics in pre-nozzle volume combustion chamber a power plant with cylindrical slot channel at mass supply surface. The simulation for objects is based on solution conjugate problem heat exchange by control method open integrated platform continuum mechanics problems (openFoam). calculation results gas-dynamic and thermal processes four-nozzle cover are presented. analysis parameters flows near nozzle cover, depending canal geometry, given. topological features flow structure thermophysical cap were studied. For first time, transformation changes channel’s geometry revealed, described, analyzed. dependence Nusselt number central point stagnation time plants operation revealed.
