ABSTRACT
Fins are widely used to increase the heat removal from a given structure. Vertical fin arrays losing heat under natural convection and forced convection find important applications in cooling electronic devices. In a few applications both modes have a contribution in cooling. In the current work, numerical analysis of mixed convection from isothermal vertical rectangular fin array, at Richardson number of unity is presented. At this Richardson number, both natural and forced convection modes are comparable. Computations are made for assisting and opposing modes of mixed convection for a range of temperature differences. Other objective of this work is to find the optimum spacing zone. For given temperature differences, Nusselt numbers are small for natural convection and become large for mixed modes, at all spacings. Optimum spacing is found for a range of temperature differences.
