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 combined processes of conduction (heat diffusion) and advection (heat transfer by bulk … Visa mer 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 … Visa mer Convection-cooling is sometimes loosely assumed to be described by Newton's law of cooling. Newton's law states … Visa mer • Conjugate convective heat transfer • Convection • Forced convection • Natural convection Visa mer Two types of convective heat transfer may be distinguished: • Free or natural convection: when fluid motion is caused by buoyancy forces that result from the density variations due to variations of thermal ±temperature in the fluid. In the absence … Visa mer The basic relationship for heat transfer by convection is: $${\displaystyle {\dot {Q}}=hA(T-T_{f})}$$ where $${\displaystyle {\dot {Q}}}$$ is the heat transferred per … Visa mer WebbIn domeniul combaterii incendiilor, fenomenul transmiterii caldurii prin convectie poate fi intalnit in diverse ipostaze. Functionarea detectoarelor termice de incendiu se bazeaza tocmai pe formarea unor curenti ascendenti de aer cald deasupra focarului de incendiu, care transmite caldura produsa, la partea de sus a incaperii.
WebbPrincipala diferență între conducție, convecție și radiație este conducerea nu este altceva decât transferul de căldură de la partea mai fierbinte la cea mai rece. Convecția este transferul de căldură prin mișcarea în sus și în jos a fluidului. Radiația apare atunci când căldura trece prin spațiul gol. Recomandat, 2024 Principal publicitate
