Description Modern manufacturing techniques have enabled much better control of internal pipe profiles adn potentially reduce pressure losses thereby optimising the design of hydraulic systems. This project investigates the use of CFD to design pipe junctions are used to divide the flow, ie T or Y junctions and the internal profiles that will enable this with a reduction in pressure loss. The project will use the ANSYS FLUENT software to model the flow in  standard Y junction geometries  of a fixed diameter and for a range of flow split variations investigate the flow patterns and pressure losses. Alternative designs will be proposed and the pressure losses determined with minimum pressure loss being sought for different flow split variations. Students should be interested in hydraulics and have a desire to develop their skills in fluid mechanics, CAD and use of CFD software Key Objectives The project has a number of objectives  (i) develop CAD models of pipe Y junction geometries for minimum pressure drop (ii) Using the literature, determine pressure loss datasets of Y junctions for comparison against CFD models. (iii) Assess the accuracy of CFD models in Y junction flows (iv) Compare CFD calculated pressure losses in Y junctions for a variety of different geometric designs
