The use of modified surfaces to improve heat transfer is quite common. When examined from a technological and economic point of view, modifying the heat transfer surface with pits is one of the most suitable techniques. After various simulations, it has been observed that the use of these surfaces in impinging jet flows negatively affects heat transfer. On the other hand, with the selection of the right geometries and parameters, it has been determined that there is an improvement in heat transfer thanks to these surfaces in wall jet simulations. However, in order to take into account the pressure drop variation, which is another important factor other than the heat transfer coefficient, the performance evaluation factor, the JF Factor, was calculated and used as a comparison parameter.
