Numerical investigation of typical valveless pulse combustor working process

Abstract

Due to the valveless pulse combustor's simplicity in structure and reliability in performance, it may be the most ideal low cost high efficient combustion system for agriclutural energy. In a typical valveless pulse combustion, a numerical simulation is performed to understand the variation of flow field and to research the performance of the valveless pulse combustor by use of general CFD simulation software (CFX). Results of numerical simulation indicate that the pulse combustor works felicitously and working process of the pulse combustor is consistent with the basic theory of the pulse combustion.
