船舶伙食冷库气流流场的分析研究
发布时间：2019-06-10 03:35
【摘要】：基于浙江某船业16500t货轮伙食冷藏库建立几何模型,以一个2.85m(长)×2.47m(宽)×2.68m(高)的实际肉库为对象,基于Fluent软件的标准k-ε模型对肉库的流场进行数值模拟。模拟结果显示,整个冷库内的流场存在一个中心大回流区,随着冷风机吹风速度的增大,流场主流越贴近壁面流动,同时冷冻库内的速度也表现处均匀和紧凑的特点。基于船舶航行对船舶冷库运行的要求,为了提高货物的冷藏质量、减少能耗,试验研究了1.8~2m/s作为冷风机最佳吹风速度的可行性,研究结果可为改善库内货架结构和优化回流区域分布提供参考。
[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.
