It should be noted that although the entrance field has no heating source at the wall (16), its bulk temperature may still vary along z due to axial conduction at both tube ends.

Modeling the forced convection heat transfer with arbitrary boundary conditions and inlet temperature profile was studied in order to go beyond the classic, but unrealistic cases of imposed uniform heat flux or wall temperature as well as a flat temperature at the inlet. The proposed approach, known as the Flexible Profile Compact Thermal Model (FP-CTM), which has been proposed earlier to treat circular cross-section ducts, is generalized here to treat ducts with a rectangular cross-section.

Conjugate heat transfer is a complex problem because heat is transferred from a solid medium to a liquid medium through their interfaces. The steady-state laminar flow formed inside the microtubules is subjected to a constant temperature at the outer sidewall surface. These images cover a wide range of wall-to-fluid thermal conductivity ratios (ksf = 1, 2, 3, 4, and 5) and wall thickness-to-inner diameter ratios (δ/Ri = 0.25, 0.5, 0.75, 1, 1.25, and 1.5) and Reynolds numbers (Re = 200, 400, 600, 800, and 1,000). The results are processed by a Fluent program based on the finite volume method to numerically integrate the driver’s differential equations. The results show that increasing the wall-to-fluid thermal conductivity ratio ksf increases the inner wall dimensionless temperature and decreases the average Nusselt number. Conversely, an increase in the ratio of wall thickness to inner diameter results in a decrease in the dimensionless temperature of the inner wall and an increase in the average Nusselt number.
