Numerical analysis of natural convection in isosceles triangular enclosure in presence of thermal radiation.

Numerical investigations are carried out to analyze the flow and thermal field induced by thermal radiation coupled with natural convection in a two-dimensional triangular enclosure. The triangular enclosure has an adiabatic right wall with left wall being administered a consistent cold temperature while the bottom wall is subjected to uniform heating. The mathematical equations of this present research article have been solved by applying a finite element strategy. A broad in content parametric research investigation is executed to assess the confrontation of (Ra) along with radiation criterion (Rd) on the fluid-transport eventuation. The numerical simulations demonstrate that Nusselt number (Nu) is an augmenting function of Ra and Rd. Consequential changes in streamlines along with isothermal contours for high Ra are realized. The present numerical investigations are applicable to solar collecting design devices, fire modeling in compartment, etc. [ABSTRACT FROM AUTHOR]
