【摘要】:基于浙江某船業(yè)16500t貨輪伙食冷藏庫建立幾何模型,以一個2.85m(長)×2.47m(寬)×2.68m(高)的實際肉庫為對象,基于Fluent軟件的標(biāo)準(zhǔn)k-ε模型對肉庫的流場進行數(shù)值模擬。模擬結(jié)果顯示,整個冷庫內(nèi)的流場存在一個中心大回流區(qū),隨著冷風(fēng)機吹風(fēng)速度的增大,流場主流越貼近壁面流動,同時冷凍庫內(nèi)的速度也表現(xiàn)處均勻和緊湊的特點。基于船舶航行對船舶冷庫運行的要求,為了提高貨物的冷藏質(zhì)量、減少能耗,試驗研究了1.8~2m/s作為冷風(fēng)機最佳吹風(fēng)速度的可行性,研究結(jié)果可為改善庫內(nèi)貨架結(jié)構(gòu)和優(yōu)化回流區(qū)域分布提供參考。
[Abstract]:Based on the geometric model of 16500t freighter food freezer in a shipping industry in Zhejiang Province, a 2.85m (length) 脳 2.47m (width) 脳 2.68m (high) actual meat depot is taken as the object. Based on the standard k-蔚 model of Fluent software, the flow field of meat bank is simulated. The simulation results show that the flow field in the whole freezer has a central large reflux zone. With the increase of the blowing velocity of the chiller, the mainstream of the flow field flows closer to the wall, and the velocity in the freezer is uniform and compact. Based on the requirements of ship navigation for the operation of ship cold storage, in order to improve the refrigerated quality of cargo and reduce energy consumption, the feasibility of 1.8~2m/s as the best blowing speed of cold dryer is studied. The research results can provide a reference for improving the shelf structure and optimizing the distribution of reflux area.
