The advantages of this method were that the measurement results were n ' t affected by flow regime and the speed was faster than the conventional voidage measurement method by reconstructed ect image 按三種流型建立模板庫,通過先進(jìn)行流型的分類,再進(jìn)行模板匹配的方法,減少了三分之二的運算量,大大加快了計算速度。
The new technique for soybean phospholipid concentrate production , such as fluidizing , bleaching and homogenizing before drying , drying with instant drying agent , and rapid cooling - deodorization - homogenization after drying , was introduced 介紹了大豆?jié)饪s磷脂在脫水前進(jìn)行流化、漂白、均質(zhì)和脫水中添加“快速脫水劑” ,脫水后進(jìn)行急冷、脫臭、再均質(zhì)的磷脂生產(chǎn)新工藝。
Examinations of steady status and analysis of dynamic experiments have been conducted on band - tube evaporator and parallel - flow condenser using r134a refrigerant . the steady examination show that the model error was under the allowable error , the inlet mass and enthalpy disturb experiments indicate that the subsection model , be good at reflecting the change of parameters of the heat exchanger , accord with the basic principle of thermodynamics theory and the actual work status . hence , the subsection simulation model research has important benefits both on theory and engineering application 在進(jìn)行仿真試驗時,以使用r134a作制冷劑的管帶式蒸發(fā)器和平行流式冷凝器為對象,完成了穩(wěn)態(tài)仿真計算、試驗和動態(tài)仿真分析,穩(wěn)態(tài)計算結(jié)果和試驗數(shù)據(jù)對比表明,其誤差在允許范圍內(nèi);進(jìn)口質(zhì)量和焓值的擾動試驗結(jié)果表明:本文所建的區(qū)段式換熱器仿真模型,能很好的反映換熱器性能參數(shù)的動態(tài)變化,與系統(tǒng)熱動力學(xué)理論和冷凝器、蒸發(fā)器的實際工作過程基本一致。
