Abstract

   In this paper, variation of temperature and velocity profiles and the angular velocity of the nanofluid flow through triangular and rectangular baffles are investigated in the existence of a uniform magnetic field. The innovation of this paper is the investigation of nanofluid parameters passing on the different baffles on the stretching surface using the Finite Element Method. According to the results of different cases, the maximum nanofluid velocity is observed in rectangular baffles. The fluid velocity for nanofluid on the rectangular baffles is 19.5% more than on other baffles. At X=0.2 to X=0.8 for rectangular baffles and triangular baffles, the average velocity of nanofluid flow in the rectangular baffles is equal to u=0.4 but, the average velocity of nanofluid flow in the triangular baffles is u=0.04. The maximum nanofluid temperature is observed in rectangular and triangular baffles. The temperature profiles of nanofluid on the rectangular and triangular baffles are 50% more than other baffles.
