This study utilizes computer aided design graphic simulation in the image processing of visualized streamlines for the jet flow through a nozzle into the atmosphere.The flow is assumed to be two-dimensional, incompressible, steady and laminar.The combination of this simulation modelling with the image processing technique proved to increase the efficiency of data processing and results in many aspects.Distributions of flow velocity, vorticity and pressure are calculated using a streamline coordinate system for governing equations.The results of CAD simulation are then compared with those obtained in applying direct image processing technique (conventional simulation) and with numerical ones for various Reynolds numbers and channel angles.
