NTU (Number of Transfer Units) method

The NTU (Number of Transfer Units) method is a way to analyze and predict the performance of heat exchangers, devices that transfer heat between fluids. It quantifies how efficiently heat is transferred by considering the size, flow rates, and temperature differences of the fluids involved. Essentially, NTU helps engineers determine how much heat can be exchanged without needing detailed temperature profiles, simplifying the design process. A higher NTU value indicates a more effective heat exchanger, allowing for better planning and optimization in thermal systems.
