ABSTRACT This paper represents the effect of staggered non-conductive partitions on natural convection heat transfer in
variable shape cavity (rectangular, trapezoidal and triangular cavities) have been studied . The three partitions mounted on upper and lower walls. The vertical walls of all cavities represents cold walls and the upper wall was adiabatic while the lower wall represents the hot wall. The numerical solution using finite difference technique to solving continuity, momentum and energy equations. The results show that the increasing in the lengths of partitions leads to reduce in Nusselt number and heat transfer for all cavities while at the same length of partition the changes in the cavity from rectangular
to trapezoidal to triangular cavities makes decreasing in the Nusselt number.
