WebbTransient Simulation. TAITherm enables you to model your product under transient conditions, giving you a real-world analysis of your design. Transient simulation offers a detailed analysis that allows you to design optimally, without over- or under engineering. Transient simulation using TAITherm is fast—delivering simulation results in hours. Webb초록. Abstract. In spite of the importance of the natural ventilation pressure(NVP) in tunnels for the optimal design of the ventilation system, there have been only few studies on the NVP because its measurement and quantitative analysis are not straightforward.
