We choose a large atrium in Beijing for the object. This dissertation builds computational models under the stratified air conditioning design schemes according to the real geometry size of the building and the calculative parameter of the air conditioning. And the CFD method is used to realize the three-dimensional simulation of the temperature field and velocity field under the different air distributions...
We discuss the dynamical simulation model of the thermal environment for automobile passenger compartments which is useful for the development of automobile air-conditioning systems. In our previous research, we proposed the model of this type considering the accuracy and the amount of computation, however, proposed model was insufficient to simulate the effect of thermal radiation and insolation...
Cold air distribution systems can potentially lower operating and first costs when compared to conventional air conditioning system. One concern for cold air distribution is that the cold supply air temperatures can be uncomfortable. Air distribution and comfort in a typical room with cold air diffusion was investigated by the method of CFD. A mathematics model was established and the air distribution...
By the steady state incompressible Reynolds-averaged Navier-Stokes equations, turbulence model, the finite volume method with interlacing of discretization, the three-dimension airflow and temperature fields inside a passenger vehicle are calculated numerically. The solar radiation and body heat are additional source term of energy equation, the influence of passenger and solar radiation on airflow...
The paper has studied features of a regional air conditioning mechanism (RACM) and CFD model to predict the comfort properties in a certain area of a workroom. The paper described the constructs of RACM, the use of computational fluid dynamics software Fluent to analyze turbulent airflow and setting up the heat transfer parameters of a certain area with RACM. As the numerical simulation of many cases...
