Heat and mass transfer of triple diffusive convection in viscoelastic liquids under internal heat source modulations

Abstract: The influence of sinusoidal (trigonometric cosine [TC]) and nonsinusoidal waveforms (square, sawtooth, and triangular) of internal heat source modulation on triple diffusive convection in viscoelastic liquids is investigated. An Oldroyd-B type model is taken into account for viscoelastic liquids. Nonlinear analysis is carried out using a truncated representation of the Fourier series. To analyze the heat and mass transfer over a triply diffusive liquid layer, expressions for average Nusselt and average Sherwoo… Show more

“…As a result, we conclude that the heat source facilitates the greatest heat transfer in the system compared to the heat sink. Further, on comparison with the most recent study of heat transfer under internal heat modulation by Noor et al, 47 the limiting case, i.e., single‐frequency internal heat modulation (χ=0;β=δ0) for a Newtonian liquid (Rs1=Rs2=λ1=λ2=0) are seen to be in great agreement with each other (Table 6).…”

“…Although many studies are available on RBC with an internal heat source, not much attention was given to studying time‐dependent internal heat source in RBC. To the best of our knowledge, the only work existing work on internal heat modulation are by Shu et al 45 and Bazylak et al 46 The most recent work by Noor et al 47 is another piece of evidence for the same. However, the authors have focused only on the impact of single‐frequency time‐dependent heat source on the amount of heat transfer in the system and have not discussed possible effect of this on the onset of convection.…”
