Week 11 - Louver/Grille characterization

Aim: To design and evaluate the flow domain comprising a portion of the Hexa grille inside the domain. To study the parametric method, the parameter trails, and the primary and compound functions to be reported for the challenge.

Introduction:

Simulations of electrical equipment, enclosed electronics components, and electrical systems are typical applications where grilles are used. The grille loss coefficient is a parameter whose value is a function not just of the free area ratio, but also of other parameters such as grille design, Reynolds number, grille thickness and flow regime (laminar or turbulent).Icepak has an automatic mode that calculates the loss coefficient as a function of the free area ratio. However, this calculation is based on empirical correlations in the fully turbulent flow regime. Since most applications are for natural convection in the transitional flow regime it is important to develop a methodology to take into account the appropriate flow regime.
