The device has also a control valve which is implemented as a liquid seal with the passage pipe meant to connect vapour volumes of the mentioned vessels, and an intermediate channel to drain the heat-transfer agent from the cold fluid vessel to the hot one, and check valves to ensure ...
1、Convection As mentioned earlier, there are three mechanisms of heat transfer: conduction, convection, and radiation. Conduction and convection are similar in that both mechanisms require material medium, but the difference is that convection requires the presence of fluid motion. And heat transfer ...
2024 That's a compelling sign that the surface is young, and refreshed by the convection of warmer ice from below. Joel Achenbach, arkansasonline.com, 20 Oct. 2024 This condensation produces more heat, leading to even more powerful convection, and the end result is known as a pyrocumulus ...
A numerical study of the steady forced convection heat transfer from an unconfined circular cylinder Forced convection heat transfer from an unconfined circular cylinder in the steady cross-flow regime has been studied using a finite volume method (FVM) im... RP Bharti,RP Chhabra,V Eswaran - 《...
Numerical study by conjugate heat transfer is carried out of solar chimney systems for heating and ventilation of dwellings. Conservation equations are solved by finite difference-control volume numerical method. The governing parameters were: the Rayleigh numbers from 5 × 10 8 to 10 11, the Prand...
生活在将来今天将是非常与生活不同。 在许多变动然后之间和现在将发生,但将是什么变动? [translate] aThe convection heat transfer coefficient is modeled as a function of the piece surface temperature 作为片断表面温度功能,对流传热系数被塑造 [translate] ...
A method of numerical solution of nonsteady two-dimensional Navier-Stokes equations in regions with curvilinear moving boundaries is proposed. As an example, the solution of the problem of melting with convection in the liquid phase is presented. DOI: 10.1007/BF01840721 被引量: 1 年份: 1985...
Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object as is the case with conduction and convection. Heat can be transmitted through empty space by thermal radiation often calledinfrared radiation. This is a typeelectromagnetic ra...
A Study of the measuring method and error of coefficient of heat transfer by convection for the interior walls have been studied using the appratus for measuring the air temperature near the surface of a wall. Quantity of heat flow by covection are assessed from multipling the air temperature ...
