DESIGN AND CFD ANALYSIS OF DIFFERENT PIPE JOINTS USED IN WATER SUPPLY INDUSTRIES

Pipe Distribution network system is very common in industries such as water supply industry, nuclear power plant industry, chemical industry, water treatments plants etc., where the fluid or gases to be transported from one location to other location. The pressure loss may vary depending on the type of components used in the total network, material of the pipe, the fluid that is being transported through the network and pipe fitting. The analysis of pipe network is very important in engineering point of view. A lot of engineering problem dealt with it. Fittings are used in pipe and plumbing systems to connect straight pipe or tubing sections, to adapt to different sizes or shapes, and for other purposes, such as regulating or measuring fluid flow. Most commonly used fitting or joints in industries are Elbow joint, T-joint and straight joint. One problem facing today’s water supply industries are flow-accelerated corrosion and erosion in pipe joints. The model geometry of three different pipe joints i.e. Elbow, T section and straight joints are created by using solid works 2016 software and the simulations are being performed using the ANSYS CFD FLUENT module after mesh were created using the ANSYS software. This report documents the results of the simulations that have been made to date; baseline results employing the RNG k-ε turbulence model are presented. Pressure, velocity, shear stress on wall, turbulent kinetic energy inner surface of elbow joint, straight joint & T - joint are shown in figures, and their values are noted and tabulated. Plots of the velocities, pressure field, wall shear stress, and turbulent kinetic energy adjacent to the wall are shown within the three different joints section
