A numerical study of entry region laminar mixed convection over shrouded vertical fin arrays

A computational study of mixed convective heat and mass transfer from a shrouded vertical non-isothermal fin array during dehumidification process

“…Since combined mixed convective heat and mass transport is significant and is not attempted by many, the same is attempted in the present article. Another important aspect of the present study is the decoupling of natural and forced convection component under mixed convection, which is highlighted recently by Bhoite et al [18], Giri and Das [19] and Das and Giri [20][21]. Pertinent literature reveals that finite thickness of fin is not paid due attention in the computational study.…”

“…One of the boundary condition is the specification of inlet velocity. After Bhoite et al [18] and Giri and Das [19], dimensionless streamwise inlet velocity (W in ) may be treated as an addition of induced and forced velocity components.…”

“…A set of equations is thus obtained in the form of tri-diagonal matrix, which is then solved by well-known Thomas algorithm. In-house numerical code developed by Giri and Das [19] is modified to suit the present problem.…”

“…Pertinent literature reveals that finite thickness of fin is not paid due attention in the computational study. Thus present study considers a problem of mixed convective heat and mass transport from vertical non-isothermal finite thickness fin array adopting the decoupling method outlined in the articles [18][19][20]. A set of rectangular plate fins, each having thickness 't f ', is glued vertically to a rectangular vertical base plate.…”

A Numerical Study of Natural Convection Heat Transfer in Fin Ribbed Radiator

“…Their results show that the number of the fins is not affected by the fin profile, but the heat transfer enhancement for the arrays with optimum fin profile is about 1-3 percent more than that for the arrays with conventional fin profiles. Giri and Das [13] numerically performed laminar mixed convection over shrouded vertical rectangular fin arrays attached to a vertical base. They found that the drop in pressure defect for forced convection, induced velocity for mixed convection and overall Nusselt number for mixed convection are correlated well with governing parameters of the considered problem.…”
