Computational Fluid Dynamics (CFD) Suite Containing Innovative AI Models For Industry Application

Technology Overview

Computational Fluid Dynamics (CFD), one form of advanced engineering simulation is widely used to design and model complex industrial applications. Examples of the use of CFD include modelling occupant’s thermal comfort in buildings design, studying aerodynamic effect for vehicle design and analysing energy distribution in industrial processes. In industrial processes, small amount of optimisation can provide large energy savings. While CFD provides high accuracy, the simulation time requires long hours that could sometimes take weeks to produce the result. As such, it is pertinent to find alternative simulation techniques which offers faster simulation time while achieving good accuracy.

The technology provider described herein has developed a collection of AI models which can replace CFD solvers to obtain faster results without increasing more computer power. Used case applied thus far includes chemical mixing processes and motorbike simulation. The technology provider is seeking for partners to collaborate through applying this simulation technique in more industry applications.
