On inclined heated square obstacle in a liquid stream carried by partially heated channel: Finite element analysis
Abstract
The present pagination is devoted to report the statistics of hydrodynamic forces towards heated square cylinder placed in between rectangular channel at various inclinations. To be more specific, the rectangular channel is considered as computational domain. The left and bottom walls are taken uniformly heated. The top wall of the channel is kept cold while the right wall is specified with an adiabatic condition. The uniformly heated square-shaped cylinder is placed in between channel with various inclinations case-wise. Further, the fluid is initiated at an inlet with the parabolic velocity profile and the outlet is carried with Neumann condition. The velocity of the bottom and top wall is taken zero. The no-slip condition at the outer surface of a square obstacle is incorporated. The whole physical design is controlled mathematically. The most reliable numerical approach named finite element analysis is utilized to examine the flow field properties. The impact of an inclination of heated square obstacle on both drag and lift forces is reported by performing line integration around the outer surface of square obstacle. The outcomes are offered by means of velocity contour plots and isotherms. Keywords: Heat transfer, Heated square obstacle, Uniformly heated walls, Hydrodynamic forces, Finite element method
