What is Nusselt Number - Definition - Thermal Engineering

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. Webwhere an overall heat transfer coefficient U [W m −2 K] is used together with a temperature driving force ΔT [K] and a heat transfer area A [m 2].This is a very common form of heat transfer expression for process applications. The computation of the overall heat transfer coefficient can be complicated depending on the complexity of the geometry and whether … WebThe equation for convection is expressed by Equation 2.5.2 which is a derivation of Newton’s Law of Cooling: Example 2.5.2 Consider a plane surface 0.4 m by 0.9 m at a temperature of 20 °C. A fluid flows over the surface with a bulk temperature of 50 °C. The convective heat transfer coefficient (h) is 1 600 W/m² °C. Radiation greek god of the sun apollo
