WebNusselt number is equal to the dimensionless temperature gradient at the surface, and it provides a measure of the convection heat transfer occurring at the surface. The Nusselt number is named after a German engineer Wilhelm Nusselt. The conductive component is measured under the same conditions as the heat convection but with stagnant fluid. WebJun 2, 2024 · Students learn about convection, conduction, and radiation in order to solve the challenge of designing and building a small insulated cooler with the goal of keeping an ice cube and a Popsicle from melting. This activity uses the engineering design process to build the cooler as well as to measure its effectiveness.
