Analysis of average Nusselt numbers at various zones for heat flow visualizations during natural convection within enclosures (square vs triangular) involving discrete heaters

Flow visualization using heat lines for unsteady radiative hydromagnetic micropolar convection from a vertical slender hollow cylinder

“…Later, couple stress thermosolutal convection along a vertical cylinder was scrutinized by Rani et al [29] using the concept of heat line and also mass line visualization. Using the same idea, recently Das and Basak [30] analysed the rate of heat transfer at different zones within enclosures involving discrete heaters. Further elaboration on the heat line methodology in thermal convection flows has been provided by Morega [31][32].…”
