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.

In this paper,we utilize SIMPLE method and S-A turbulent model to solve the three-dimensional incompressible Reynolds-averaged N-S equation.

It used the SIMPLE method for gas and PISC algorithm for calculating gas-solid coupling.

The model was established on the basis of the Finite Volume Method and the SIMPLE method.

The process of reprogramming SIMPLE program is described in detail based on new trait of Fortran95,which involves main program,user subroutine and other subroutines.
