Heated Laminar Gas Flow in Annuli with Temperature-Dependent Transport Properties

Laminar Forced-Convective Heat Transfer with Varying Properties in the Entrance Region of Flat Rectangular Ducts

“…. Shumway and McEligot [13] extended the previous work to show significant variations in the properties of air for high heating rates through tube annuli.…”

“…The properties were allowed to vary according tõ s. (10)- (13). Since the inlet boundary conditions.…”

“…iNTRODUCTION A number of numerical studies of simultaneously developing laminar velocity and temperature fields ih the entrance region of a tube or parallel-plate channel have appeared in the literature [1][2][3][4][5][6][7][8][9][10][11][12][13]. Such studies have been motivated by a growing interest ih the application of compact heat exchangers where equivalent diameters are small, especially with gas flows, and the heat exchanger design range falls well I within the low Reynolds number regime (Red < 2300).…”

Laminar Mixed Convection in the Entrance Region of a Horizontal Annulus

“…Coney and ElShaarawi [I21 have presented these results graphically, and the present results are in good agreement with them. As an additional check, the forced convection solution was obtained for an annulus with radius ratio of 4 and compared with the results of Shumway and McEligot [13]. Again, the agreement was within 1-2%.…”

Prediction of laminar and turbulent flow heat transfer in annular passages

“…(3. 15) was satisfied for the momentum equation. A rigorous stability analysis for the finite-difference representation of the turbulence kinetic energy equation was therefore not warranted.…”
