SYNOPSIS

“Computational Fluid Dynamics (CFD) has evolved tremendously in almost all areas where fluid and heat transfer is a concern. CFD is a computational art of solving control volumes of any fluid flow domain defined. In order to do that the governing equations ought to be derived which describes a fluid flow.

It can be said that physical property of any fluid motion are governed by three basic principles: Conservation of mass, Newton’s second law (F=ma), Conservation of energy. These three principles can be expressed in the form of basic equations, which are either integral equations or partial differential equations. Then, the CFD would be the technique of replacing the integral and differential equations with discretized algebraic forms, which then was solved to obtain answers in the form of numbers of the flow at discrete points in time or space or both. The problem further complicated with addition of turbulent state prediction, multi-phase fluid flow, combustion, heat transfer and so on.

CFD tool has already been accepted in Building services industry as a tool of solving future problems. It solves anticipated problems during design stage and solves existing problem in operational stage. This talk will cover a design stage experience sharing of utilizing CFD as tool for natural ventilation simulation with Building Energy simulation, Fire simulation for performance based design, and the heat distribution at outdoor air-conditioning units and cooling towers.

The validity of CFD results in real world problems and the flexibility of the model development on the building and air conditioning components, will definitely benefit the Building services community in making sure successful and green virtual designs.
