The objective of the current study is to investigate the importance of entropy generation and thermal radiation on the patterns of velocity,isentropic lines,and temperature contours within a thermal energy storage device filled with magnetic nanoencapsulated phase change materials(NEpCMs).The versatile finite element method(FEM)is implemented to numerically solve the governing *** effects of various parameters,including the viscosity parameter,ranging from 1 to 3,the thermal conductivity parameter,ranging from 1 to 3,the rayleigh parameter,ranging from 102 to 3×10^(2),the radiation number,ranging from 0.1 to 0.5,the fusion temperature,ranging from 1.0 to 1.2,the volume fraction of NEpCMs,ranging from 2%to 6%,the Stefan number,ranging from 1 to 5,the magnetic number,ranging from 0.1 to 0.5,and the irreversibility parameter,ranging from 0.1 to 0.5,are examined in detail on the temperature contours,isentropic lines,heat capacity ratio,and velocity ***,the heat transfer rates at both the cold and hot walls are analyzed,and the findings are presented *** results indicate that the time taken by the NEpCMs to transition from solid to liquid is prolonged inside the chamber region as the fusion temperatureθf ***,the contours of the heat capacity ratio Cr decrease with the increase in the Stefan number Ste.

在pantnagar采用裂区设计,在试验规定条件下,从七个玉米杂交种第二代分离的果穗中选出的正常玉米和0-2玉米子粒,测定了在不同的取样日期子粒含水量、水分丢失、水份减少的百分率和水分丢失率。结果表明:0—2种群含水量比正常玉米为高,然而,不同的遗传背景0—2基因有易变的效应。4天间隔期间,最后4天间隔除外,0-2水分丢失也如含水量降低一样比正常玉米为多。0—2种群比正常玉米水分丢失率为高。然而在两个基因型中差异是显著的。本资料表明了采用相等的干燥率,有可能获得0—2玉米品系。
