![]() ![]() The model is then combined with a two level factorial design to identify the significant factors as well as the potential interactions using the numerical simulation results. The effect of several important parameters, namely, position of the opening, initial relative humidity inside the enclosure, length and radius of the opening and temperature is studied using the developed CFD model for the isothermal case. It is shown that the RC method predicts a faster trend for the moisture transfer into the enclosure compared to the CFD. In the first attempt, an isothermal case is developed and compared against the well-known RC circuit analogy considering the behavior of an idealized electronic enclosure. In this work, a computational fluid dynamics (CFD) model is developed to simulate moisture transfer into a typical electronic enclosure. Thus, it is important to control the moisture content and the relative humidity inside electronic enclosures. Condensation and moisture related problems are the cause of failures in many cases and consequently serious concerns for reliability in electronics industry. ![]()
