In thermal fluid dynamics, the Nusselt number ( Nu, after Wilhelm Nusselt [1] : 336 ) is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection (fluid motion) and diffusion (conduction). The conductive component is measured under the same conditions as the convective but ... score in rams 49ers gameThe basic relationship for heat transfer by convection is: $${\displaystyle {\dot {Q}}=hA(T-T_{f})}$$ where $${\displaystyle {\dot {Q}}}$$ is the heat transferred per unit time, A is the area of the object, h is the heat transfer coefficient, T is the object's surface temperature, and Tf is the fluid temperature. The … Ver más Convection (or convective heat transfer) is the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the … Ver más Two types of convective heat transfer may be distinguished: • Free or natural convection: when fluid motion is caused by … Ver más • Conjugate convective heat transfer • Convection • Forced convection Ver más Convection can be "forced" by movement of a fluid by means other than buoyancy forces (for example, a water pump in an automobile engine). Thermal expansion of fluids may also force convection. In other cases, natural buoyancy forces alone are entirely responsible … Ver más Convection-cooling is sometimes loosely assumed to be described by Newton's law of cooling.
