Abstract: The project deals with the computational fluid dynamics analysis of mixed flow of hot and cold water in T- pipes and it is mainly concentrated on analytical approach to the areas where Pipes (used for flow) are mostly susceptible to damage. The simulation is done on T-pipe by placing the nozzle at three different places, to know the pressure, temperature and velocity contours throughout the flow and comparison was made. These T- pipes are mostly used in nuclear reactor cooling system to reduce the heat in the nuclear reactors by mixing hot and cold water, where the mixing will takes place efficiently. And mixed flow at the outlet will take heat from the inlet also due to convective heat transfer loss; the temperature at the boundaries of the T- pipe will be reduced. The 2D model of the pipe is made by GAMBIT and analysis is to be carried out by using K-Epsilon in FLUENT software. The models are first generated using the data and then various velocity, temperature and pressure contours are to be drawn and graphed to analyze the flow through the pipe
