Numerical modeling and experimental investigation of minichannel heat exchanger to evaluate flow and thermal characteristics of nanofluid

Heat transfer characteristics is a major subject that has been extensively studied by researchers and different methods for optimal heat transfer have been investigated. In this study, experimental and numerical methods have been utilized to evaluate thermal performance of aluminum cooling blocks operated by recycled nanofluid. New generation stable nanofluid Fe3O4/Water was used as heat transfer fluid in the cycle. In the experiments, the operating conditions such as flow rate, volume fraction of the nanofluid and fluid inlet temperatures were changed to find the effect of each parameter on the thermal efficiency. In this research, the problem has been solved using numerical simulation and required diagrams have been presented in the form of temperature and velocity contours. ANSYS/Fluent software has been used to simulate the model.
