To explore the propagation of turbulent flame in a large horizontal tube,numerical simulation has been carried out by the using of homogeneous fluid model, the standard k ε turbulent model, EBU Arrhenius combustion model and two dimensional homogeneous reaction model, and Simple scheme is adapted to solve the models.

Solution for conservative equation of 2-D shallow flow by using revised SIMPLE algorithm;

The wind flow model and Eulerian approach are used to simulate airflow pattern and large eddy simulation of turbulent flow is conducted while SIMPLE method is employed to solve the wind flow field.

Through examples,this paper introduces three kinds of exponential smoothing,namely Simple method,Holt method and Winters method.

An improved SIMPLE algorithm used in numerical simulation of flammable gas cloud deflagration;

Nonorthogonal collocated grid-based SIMPLE algorithm;

A new modification to SIMPLE algorithm;

By the use of a CFD software--PHEONICS, this paper introduces SIMPLE arithmetic to solve N-S equation, simulates the smoke flow,heat-transfer and combustion process as fire in underground garage, and obtains the vectorgraph of smoke,velocity and temperature.

Finite volume method is used to discrete the equations and the SIMPLE arithmetic is adopted to slove the equations.
