Summary, etc The study of heat and mass transfer in heated parallel channels is relevant to wide variety ofapplications such as solar air heaters, cooling of electronic equipment and nuclear reactors, solarchimneys etc. and thus a wide body of literature is available. However, only a few studies areavailable for heat and mass transfer in heated asymmetric channels which are also of practicalimportance such as in PV panel cooling design, building facades etc. In the present study,numerical investigations are carried out using ANSYS FLUENT for various configurations ofasymmetrically heated 2-D full as well as half convergent and divergent channels. All proper-ties of the fluid (air) are assumed constant except small density variations due to temperaturedifference which gives rise to natural convection and can be modeled using Boussinesq approx-imation. At first, laminar natural convection is modeled for flow in heated parallel channels atdifferent inclination angles and aspect ratios to validate the numerical methodology. The aver-age Nusselt number, convective heat transfer coefficient, mass flow rate and heat transferred toair is studied for all the cases for different Rayleigh numbers and validated with the previousliterature available. This is followed by study of laminar flows in convergent configurationswith asymmetric heating. Next, turbulent natural convection in these channels is investigatedand compared with parallel channel configuration for the variation in mass flow rate and heattransfer. Lastly, as in natural convection the mass flow rate cannot be prescribed, turbulentforced convection with fixed mass flow rate is also investigated for the parallel, half convergentand half divergent channels. This also includes radiation heat transfer which is modeled us-ing Discrete Transfer Radiation Model. It is observed that in all cases parallel channel flowconfiguration results in maximum heat gain of the air flowing through.<br/>
