Abstract

Adopting kε double equation turbulent model

QUICK format

CIMPLE algorithm

and nonuniform crossed grid system

the numerical simulation of three dimensional cold flow field in combustion chamber of Wshaped flame boiler has been carried out

giving out flow field diagram and velocity profile of the typical crosssection

having brought to light the main physical properties of flow in combustion chamber of said boiler. Practical example of calculation shows that the QUICK format and CIMPLE algorithm used simutaneously to numerical simulation of turbulence backflow can give consideration to the speed of numerical simulation at the same time

under conditon of ensuring higher precision of numerical simulation.
