E. Mebunii April, 2024. Convective heat transfer coefficient h (or hc), is a measure of the thermal resistance of a thin layer of relatively immobile fluid, which is sandwiched between a solid heat exchanger and a fluid medium. This immobile fluid layer is often called the boundary layer [ 3 ]. It may also be described as a measure of the ... WebConvection also known as convective heat transfer is heat moved by the movement of gasses or liquids. Two types exist, i.e. forced and natural convection. Natural convection is when the fluid movement is created by buoyancy forces due to changes in fluid density. One example is heating water in a pot. floral delight meaning
