| Popis: | The present pagination is devoted to report case study on an examination of hydrodynamic forces experienced by partially heated circular obstacles in a grooved channel. To be more specific, the channel is considered as a computational domain. The heated rectangular ribs are introduced to attain grooved geometry. The two partially heated circular-shaped cylinders are placed in between channel as obstacles. The fluid is initiated with the parabolic velocity profile from an inlet. The outlet is carried with both Neumann and adiabatic conditions. The mathematical model is constructed to narrate the flow field. The solution is obtained by using the finite element method. The outcomes are shared in terms of velocity and temperature contour plots. The impact of the change of the distance between the partially heated circular obstacles is debated on both drag and lift coefficients.
