Analytical Solution Developed for Optimizing Double-Pipe Flow Systems

Abstract

In the present study an equation has been developed to estimate the optimal design diameters of double-pipe flow systems . The equation is based on hydraulic and economic considerations and is applicable in annular flow turbulent regions. The equation is tried on data obtained from an experimental work , conducted on a specified annular flow system . The equation gives good results as illustrated from computations and has revealed that, considerable reductions have been achieved in pipe, pumping and pump costs by the selection of the optimal diameters of the double-flow pipe system
