In the past few decades, state-of-the-art technologies for heat transfer have been considerably developed to have more performable systems in industries. Among the available solution to increase the thermal performance, the use of nanofluids can be considered due to their high thermal performance. In the present work, a numerical investigation has been carried out on impingement jet with nanofluid to study its fluid dynamics and thermal performance. In this paper, the working fluid is considered a boehmite alumina nanofluid with a base fluid of water and ethylene glycol mixture (50:50). The impact of changing in Reynolds number, the volume fraction, and shape of nanoparticle such as spherical, plate, blade, cylindrical and brick shapes on heat transfer, and the dynamic of flow have been examined. The outcomes of the current study indicated that heat transfer raises as a result of increasing in the Reynolds number and volume fraction. The maximum Nusselt number and the maximum of heat transfer occurs in the cases with platelet and cylindrical nanofluids. On the other hand, the minimum heat transfer rate occurs in the cases with nanofluids with spherical nanoparticles. Also results showed that at volume fraction equals to 2% and 4%, the Nusselt numbers of nanofluid contains platelet particles are about 28.96% and 83.3%, more than the spherical particle nanofluid, respectively.
