Numerical simulation of upside air - supply bottom - side air - return symmetric ventilation in space station cabin 空間站艙內側上送側下回對稱通風方式數(shù)值模擬
The improved option is put forward with adjusting air - supply velocity and change its angle 在此基礎上,進一步提出了調整送風速度,改變送風角度的改進方案。
With the momentum method of air - supplying openings , four typical operating conditions in the case of each air - supplying way are simulated 模擬利用風口的動量描述方法對每一種送風方式采用了四種典型的工況。
Therefore , the thesis putts forward a preliminary modifying air conditioning design option , which can improve the whole comfort character of guest rooms , by selecting fan - coils units rationally , adjusting air - supply angle and decrease air - supply velocity 為此,本文提出了合理選擇風機盤管、調整送風角度、減小送風風速,提高客房整體舒適度的空調設計初步改進方案。
In this article , simulations of air distribution in the vav air - conditioned office are carried out in the cases of different air - supplying diffusers including slot diffuser , sqaure grille , bar grille and square diffuser to supply air , the standard three - dimensional k - ? two - equation turbulence model with correctional item of buoyancy effect and simple algorithm are adopted , and wall function method is used to handle boundary conditions 本文采用經(jīng)過浮升力項修正的-兩方程模型和simple算法,應用壁面函數(shù)法處理邊界條件,對利用包括條縫風口、方型百葉風口、長條型百葉風口和方型散流器不同型式送風口送風的變風量空調房間內的氣流組織進行了模擬。
Then the air distribution system of the above - mentioned hotel ' s multi - function - hall was simulated with fidap , and the indoor temperature and velocity under the preliminary option was calculated . under the half - load condition of small air - supply quantity and slow velocity , finds that the problem has arisen , which the cold jets fall too fast in summer and the air distributes layer upon layer in winter 然后應用fidap對上述旅館的多功能廳空調氣流組織初步方案進行了數(shù)值模擬計算,預測了該初步方案的室內溫度、速度分布,發(fā)現(xiàn)在送風量和送風速度小的半負荷工況下,會出現(xiàn)夏季送風時冷射流過早下降,冬季送風時氣流分層分布的現(xiàn)象。
