hot starch solution is being cooled from about 60 deg C to 30 deg C..... but possible channeling occuring... leading to the temperature on the outlet starch pipe not being uniform.not sure on how to conduct the energy balance using a plate heat exchanger... please add units and equations in solution that it can be followed.
What do you mean by the outlet temperature not being uniform. Do you mean not the same over time? Or are there multiple outlets and the temperature from each outlet is not the same? If the inlet and outlet channels or headers are not designed carefully to allow for good fluid dynamics then there can certainly be portions of the exchanger that is not getting the same flow as other portions. Without more information, I can not see how an energy balance will help solve the problem.
