where: dT/dz is the temperature gradient, α is the thermal expansion coefficient of the melt, g is the acceleration of gravity, l is geometric scale of the container, γ is the dynamic viscous coefficient of the melt, and k is the thermal conductivity of the melt. The Rayleigh number de...
A film coefficient (convection) boundary condition simulates exposure to external flow, without actually modeling the air that surrounds it. A higher value of film coefficient would be used to simulate a forced convection situation. Applying this condition is a little tricky because we need to...
Coefficient of viscous, pressure and total drag Cp : Surface pressure cp : Fluid specific heat capacity (Jkg−1K−1) d : Diameter of cylinder (m) H∞ : Uniform magnetic field (wbm−2) M : Interaction parameter Mcr : Critical interaction parameter Nu : Local Nusselt number ...
Panel (c) shows a scatter plot of U50 vs. Niño3.4, and the level of T50-100 is presented in colors. All values are wintertime mean anomalies for December to February (DJF), and the correlation coefficient between variables of x and y axes is shown above each panel. The number next...
coefficient is small, then the temperature of the fluid phase was lower than that of the solid phase. Badruddin et al.24also conducted a study on the effect of thermal-natural convection in a square porous cavity using LTNE approach. The onset of convection in a nanofluid saturated porous ...
coefficient. However, in the case of pebbles, stones due to significant frictional pressure drop free convection are found better than forced convection. In Free convection, the highest thermal efficiency is recorded for iron scrap heat storage material (69.8%). Similarly, in forced convection ...
N Sheriff,P Gumley - 《International Journal of Heat & Mass Transfer》 被引量: 104发表: 1966年 Turbulent heat and mass transfer from a wall with parallel roughness ridges As it is known, the general equation for the coefficient of heat (or mass) transfer between a rough wall and a turbul...
They investigated the droplet in the different Rayleigh numbers and diameters of the drop on the heated wall. Zarringhalam et al.10 studied the influence of nanoparticles concentration and Reynolds number on the pressure drop and heat transfer coefficient of CuO/Water nanofluid in the turbulent flow...
The NEPCMs consist of the core and the shell. The cores are made of a Phase Change Material (PCM). It solidifies or melts at a special temperature called s fusion temperature. The shell consists of a polymer. The NEPCM suspensions are a new form of hybrid nanofluids. It has several ...
