Visualization Area

Bharath

Hello there

I have been working on Spray modelling and It is required to obtain a Uniformly Distributed Fine Spray at the Exit of the nozzle.To achieve this..I tried to extend my nozzle exit by constructing an Visualisation area of order 100mm*60 mm ( and gave pressure outlet conditions at the edes )while my nozzle dimensions are of the order 1-5 mm....do u think such a big Visualization area is required to see the flow at the exit ?..would it have any impact on the Convergence of the program and hence the modelling ??

Thanks
