Abstract

This paper presents a powerful surface based techniques for experimental work of complex flow fields resulting from towing tank method, these flows have a characteristics which is independent of the medium and its velocity, but depends only upon a parameter called Reynolds numbers which is a non dimensional number formed by the velocity, geometrical parameter and kinematic viscosity of fluid. There are many situations where one needs to compare with two or more data sets. it may be experimental results, physical parameter, flow visualization through photographs and so on. This paper focuses on the comparative flow visualization (Streamline) of vortex flow between two different fluids like water and diesel by identifying the physical parameter using towing tank based experimental setup and also predict the experimental results with MINITAB for the regression analysis.
