This paper presents a numerical simulation based on computational fluid dynamics (CFD) method on the enhancement of natural ventilation in an industrial workshop with heat source induced by solar chimney (SC). Four types of SC were designed to attach to the top and southern roof of the workshop. Realizable k-ε turbulent model and DO (discrete ordinate) radiation model were used to calculate the air...

Harmful substances emitting from aluminum electrolysis process may pollute the environment. Ventilation is the effective means to control the hazards. In order to obtain the best ventilation effect for 300kA aluminum electrolysis plant, CFD method is used to simulate and optimize the workshop ventilation. Based on theoretical analysis and preliminary calculation, a 3D model is built, five kinds of...
A new energy-saving type of air-conditioning named large and small zone ventilation for loom workshop is proposed in authors' preliminary work. There are four factors which effect greatest large and small zone ventilation and are concerned by most designer and operators. These factors are: relative humidity of air-inlet in working area, speed of air-inlet in working area, relative humidity of background...
The method of ventilating system optimization for Roots Blower workshop has been studied according to the problem of bad ventilating effect with the transmitted medium of carbon monoxide in a chemical factory based on computational fluid dynamics (CFD). An optimized ventilating system has been designed and carried out as follows: the ventilating system is effective with the cooling air flowing in...
