ABSTRACT: Fluid flow optimization of an 8-parameter flow manifold for skewed flow distribution is dealt in this paper. We deal with a one-by-four manifold. We have to optimally locate the guide plates. The objective of the work is to minimize the standard deviation of the actual flow rates from the set points by controlling 8 parameters four of which are lengths and four of which are angles of deflection. The set points are flows in ratios of 40:30:20:10. We take the input as the 60 data points generated by the process of CFD. Using the combination of ordinary least squares and genetic algorithms we develop the minimization algorithm for the objective function. We have successfully evaluated the objective and 8 parameters for skewed flow distribution. Since we needed to achieve skewed distribution, the guide vanes were found to have greater role in offering resistances in flow apportionment as compared to the case of equal flow distribution, thus serving as high value resistors in the manifold circuit
