Thermal influence of homogeneously heated Y- shaped flipper on flowing stream in an unwavering rectangular domain

Abstract

The current study offers the numerical findings on uniformly heated Y-shaped fin embedded in a rectangular domain having height 0.6 m and 2 m length. The no-slip condition is carried at left, upper and lower wall of channel. These walls are taken cold as well. Both the Neumann and adiabatic conditions are implemented at the right wall. The cold Newtonian fluid enters with the parabolic velocity profile from inlet of channel. The problem is controlled mathematically in terms of partial differential equations. The finite element method is adopted along with hybrid meshing scheme to report acceptable solution. The velocity, pressure and temperature distributions around the heated Y-shaped fin are offered graphically. The temperature findings are reported for the cold, adiabatic and heated tips of Y-shaped fin. The line integration around Y-shaped fin is performed to evaluate the lift and drag coefficients values. The lift coefficient and drag coefficient corresponds the lift force and drag force experienced by the heated Y-shaped fin. It is observed that for the higher values of Reynolds number the lift coefficient shows an inciting values while the drag coefficient shows decline nature.
