針對理論解析結果與實際熱傳遞行為存在的差異作了詳細的分析,對經典的fourier定律所隱含的無限大熱量傳播速度、成立的基礎及在微小尺度瞬態熱傳導過程中應用所存在的不足等情況進行了分析。Numerical results are obtained for velocity, temperature and concentration profiles, variations of both nusselt and sherwood numbers under different buoyancy ratio and inclination angles of = 15 - 90. at a given inclination angle, heat and mass transfer rates decrease with heat and mass buoyancies and the buoyancy ratio b decrease from high positive values, and then increase again with the buoyancy radio b further decreasing after the velocity and transfer rates reaching a minimum
研究結果表明:傾斜角度一定,當熱浮力與物質擴散浮力共存且二浮力之比b從較高正值變化到較高負值時,流體速度和熱質傳遞速度從高逐漸變低並出現最小值,此後隨著向下浮力的增大,流體向下流動且隨| b |的增大而加速,熱質傳遞速率隨| b |的增大而重新增大。The nusselt and sherwood numbers increase with the increasing buoyancy ratio of b. when b reaches bmin, nusselt and sherwood numbers are attained minimum. the value of buoyancy ratio bmin which is a function of pr / sc increase with the increasing pr / sc and bmin varies drastically when 0 < pr / sc < 2
流體速度和熱質傳遞速度出現最小值時即nusselt數和sherwood數為最小值時的浮力比為b _ ( min ) ,它是普朗特數和施米特數之比pr / sc的函數,隨pr / sc的增大而增大。Results showed that temperatures have different effects on the curing speed of resin, the rate of moisture transmission, the degree of plastic melting and the degree of wheat straw decomposition
