This study analyzes the convection heat transfer to a micropolar fluid in an enclosure with varied heating lengths and locations. The left wall is heated to higher temperatures, either fully or partially, while the right wall remains cooler. The heater is placed at three different positions along the left wall, and insulation is applied to the non-active areas. Using the finite volume method, the research investigates the effects of heater length, position, and material parameters, such as the Prandtl number and Rayleigh number. Results shown in graphs of Nusselt numbers, isotherms, and streamlines indicate that the mean Nusselt number decreases with increasing material parameters. Additionally, a shorter heating section enhances average heat transfer, particularly when the heater is located at the wall's lower part.
