CFD Analysis

CFD Analysis (Computational Fluid Dynamics)

When a problem is too complex to predict the results by analytical calculations alone, numerical approach is used to solve the problem. Excessive or narrow flow paths can cause undesirable flow phenomena such as dead zones, low velocity zones, short circuiting, recirculation’s, leading to reduction in performance and hydraulic efficiency of the tank. Computational Fluid Dynamics (CFD) is a method to analyse the fluid flow behaviour in the domain using a Computational method to solve the governing equations numerically.

• Computational fluid dynamics (CFD) can simultaneously predict fluid flow, vortex formations and velocity distributions and dead or re circulation zones.
• A CFD model is built upon fundamental physical equations of fluid flow, momentum and energy transfer.
• However, appropriate assumptions and approximations are made both in formulating and constructing a CFD tool, as well as in its application to a particular flow problem.
