摘要：
In this paper, errors. of variable Nu number in forced ventilation CFD simulation are analysed using verification and validation respectively. These errors include modelling errors which originate from hypothesis and approximation of physical models and numerical errors which are introduced during the numerical calculation of mathematical equations. Verification is the process of estimating numerical errors of simulation. Validation is the process of estimating modelling errors. The calculation methods of verification and validation were briefly introduced. Using these two methods, the adaptability of several turbulence models in forced ventilation is discussed.
