Prandtl number scalings for unsteady natural convection boundary-layer flow on an evenly heated vertical plate in a homogeneous Pr > 1 fluid

Influence of undulating wall heat and mass flux on MHD natural convection boundary layer flow from a vertical wall

“…Another analytical study was conducted by Das et al 10 to investigate the radiation effect on the BL flow over a porous semi‐infinite plate. Prandtl number scaling of natural convective BL flow of homogeneous fluid was conducted by Lin and Armfield 11 …”

“…Prandtl number scaling of natural convective BL flow of homogeneous fluid was conducted by Lin and Armfield. 11 The unsteady mixed convective BL flow close to a wedge was numerically carried out by Roy et al 12 They considered both the free stream velocity and wall temperature to be oscillated about a nonzero steady value. Results revealed that the amplitude of the skin friction and heat transfer grow larger close to the leading edge because of higher values of the Richardson number.…”

Scaling laws for natural convection boundary layer of a Pr > 1 fluid on a vertical solid surface subject to a sinusoidal heating flux in a linearly stratified ambient

“…with the linear regression coefficient of R = 0.9988 2 . This clearly shows that the scaling (29) for v m T s , , is valid.…”

“…All numerical simulations were conducted with our in-house code used in Reference [11,28,29] and a series of our other past studies, such as References [10,36,48]. As the numerical methodology, meshes, benchmarking of the code, and so on, were detailed in those papers, particularly in References [11,28] they will not be presented here to avoid repetition.…”

“…We follow the same procedure as taken by us in the past studies on the unsteady NCBL flows with different heating conditions and configurations, in particular that in References [11,16,28,29,36]. Some details in the following scaling analysis are therefore not repeated as they can be found in these past studies.…”
