Effect of waviness on thermal-flow characteristics in an inclined trapezoidal cavity filled with nano-encapsulated phase change material and water

This study examines the free convection in an inclined trapezoidal enclosure generated by a temperature difference between a flat cold wall and a wavy hot wall. The trapezoidal enclosure is filled with hybrid nanofluids. This new type of fluid consists of nano-encapsulated phase-change material (NEP...
