This paper presents a comprehensive computational work on the hydrodynamic, thermal, and mass transfer characteristics of a circular cylinder, subjected to confined flow at the cylinder Reynolds number of $Red=40$. As the two-dimensional, steady and incompressible momentum and energy equations are solved using ANSYS-CFX (version 11.0), the moisture distributions are computed by a new alternating direction implicit method based software. The significant results, highlighting the influence of blockage $(\beta =0.200\u20130.800)$ on the flow and heat transfer mechanism and clarifying the combined roles of $\beta $ and moisture diffusivity $(D=1\xd710\u22128\u20131\xd710\u22125\u2002m2/s)$ on the mass transfer behavior, are obtained for practical applications. It is shown that the blockage augments the friction coefficients $(Cf)$ and Nusselt numbers (Nu) on the complete cylinder surface, where the average Nu are evaluated as $Nuave=3.66$, 4.05, 4.97, and 6.51 for $\beta =0.200$, 0.333, 0.571, and 0.800. Moreover, the blockage shifts separation $(\theta s)$ and maximum $Cf$ locations $(\theta Cf\u2212max)$ downstream to the positions of $\theta s=54.10$, 50.20, 41.98, and 37.30 deg and $\theta Cf\u2212max=51.5$, 53.4, 74.9, and 85.4 deg. The highest blockage of $\beta =0.800$ encourages the downstream backward velocity values, which as a consequence disturbs the boundary layer and weakens the fluid-solid contact. The center and average moisture contents differ significantly at the beginning of drying process, but in the last 5% of the drying period they vary only by 1.6%. Additionally, higher blockage augments mass transfer coefficients $(hm)$ on the overall cylinder surface; however, the growing rate of back face mass transfer coefficients $(hm\u2212bf)$ is dominant to that of the front face values $(hm\u2212ff)$, with the interpreting ratios of $h\xafm\u2212bf/h\xafm=0.50$ and 0.57 and $h\xafm\u2212ff/h\xafm=1.50$ and 1.43 for $\beta =0.200$ and 0.800.
