“…The concept of simple thermal model proposed by Ahamad and Balaji (2015) is used in the present study by replacing the discrete heaters by a uniform heat generating volume. The thickness of simple thermal model is same as that of discrete heat sources.…”

“…The isothermal condition on all the heaters is achieved at a particular velocity for both aluminium and copper metal foams. Ahamad and Balaji (2015) studied laminar conjugate mixed convection through distinct heater sources by applying simple thermal model concept. They revealed that the geometric complexity can be reduced by applying simple thermal model concept instead of discrete heat sources which result in uniformly distributed heat in the domain.…”

In this work a forced convection through discrete heat sources and simple thermal model placed inside the vertical channel is analyzed numerically. The problem considered for the investigation comprises of a vertical channel with distinct heat source assembly located at the center of the channel. The novelty of the present work is to replace the discrete heat source assembly by a simple thermal model to obtain uniformly distributed temperature and streamlines. A conjugate heat transfer investigation is carried out because the problem domain consists of aluminum solid strips as well as Bakelite strips in discrete heat source assembly which are replaced by a aluminum solid in case of simple thermal model. The numerically obtained data are initially compared with experimental data for the purpose of validation. The temperature of each discrete sources decrease with increase in inlet velocity of the fluid and bottom heat source is able to take higher heat load. The results in terms excess temperature obtained for both discrete heat source and simple thermal model is presented and discussed.

“…Roy and Das (2019) studied the effect of property variation on fluid flow and heat transfer for natural convection from a vertical fin array. Ahamad and Balaji (2015) investigated heat transfer from vertically kept heat protruding sources. Again, the mixed convection heat transfer is investigated by Ajmera and Mathur (2015) and Chen et al (2017) for multiple ventilated enclosures with discrete heat sources and fluid flow characteristics, respectively.…”

Purpose The paper aims to investigate the influence of the angle of inclination on mixed convection heat transfer from rectangular plated shrouded fin array computationally. This study has got applications in the various thermal field such as cooling, solar thermal and so on. Design/methodology/approach A computational study is made to evaluate the thermal performance in an inclined channel. Findings Increase in clearance from 0.01 to 0.25 results in an increase of local Nusselt number by is as high as 15% near the exit. At a higher value of Gr with an increase in C* from 0.10, Nu is found to increase by 5.5%. Increase in Gr by 1.37 times results in enhancement of Nu by a maximum of 25-30%. Around 10% increase in overall Nu value is observed with an increase in inclination (i.e. from 30° to 60°). Practical implications This study has got applications in the various thermal field such as cooling, solar thermal and so on. Originality/value Entry region mixed convection in a shrouded inclined finned channel is performed.
