Numerical simulation for convergent air curtain under undisturbed area condition

Abstract

The formation of an "invisible, transparent, insulated airtight cover" from the convergent air curtain between pollutants and operator control pollution equivalent to increase a sealed cover to prevent the outward diffusion of pollutants, which cut off heat passed out at the environmental protection, labor protection, and health protection, is very beneficial and also has great application value in life. In this chapter, under static conditions, the air curtain in a different angle of incidence, the width of the initial wind speed, to use AutoCAD to set air curtain model, meshed it with Gambit and solved it by FLUENT software, then drawn a simulation model. On the other hand, to analyze the experimental results by the numerical simulation, software Origin was used to analyse the convergent effect of the air curtain with undisturbed outward conditions. The varying parameters are incident angle and the width of the air curtain. The incident angle, the relationship of the width of the air curtain. Gotten that the best range air curtain incident angle under undisturbed conditions is from 68 to 74, laid the theoretical and experimental bases for the actual applications of convergent air curtain. © Springer-Verlag Berlin Heidelberg 2014.
