Price Industries Limited是北美暖通空调（HVAC）设备设计和制造的领导者，需要提高紧凑型送风风扇装置的性能。该装置通常用于为加热和冷却 ** 负载变化的建筑区域提供气流。**该装置由外壳、电子面板、小型离心风扇、风扇外壳和电机组成。风扇装置性能的 ** 改进将为客户带来显著的长期节能效果。**不清楚需要对设计参数进行哪些改变来实现改进的性能。这可能需要对外壳、风扇外壳和风扇叶片进行组合更改。通过实验探索这些变化可能涉及许多昂贵且耗时的试错测试。该公司希望能够使用CFD（计算流体动力学）建模来探索设计 ** 变化，从而优化风扇装置。CFD分析将预测装置中的三维空气 ** 流。之后，在优化过程中，可以改变几何形状和风扇参数，并通过软件详细预测 ** 产生的性能。这一能力将通过缩短设计周期并使公司在该产品 ** 类别中更具竞争力，为Price Industries带来经济效益 **。然而，第一步是为当前的风机装置配置获得可靠的CFD模型。**本项目的目标是使用商业 ** 软件开发风机装置的稳态CFD模型，并验证该模型。模型参数将有所不同，并将与现有的内部 ** 实验数据进行比较。

Price Industries Limited, a Manitoba-based leader in North America of the design and manufacture of heating**ventilating, and air-conditioning (HVAC) equipment, needs to improve the performance of a compact air**supply fan unit. The unit is commonly used to provide airflow to building zones where the heating and cooling**loads vary.**The unit consists of a casing, an electronics panel, a small centrifugal fan, the fan housing, and a motor. The**improvement of the performance of the fan unit will lead to significant long-term energy savings for customers.**It is not obvious which changes to design parameters are required to achieve the improved performance. It may**require a combination of changes to the casing, fan housing, and fan blades. Exploring these changes**experimentally could involve many costly and time-consuming trial-and-error tests.**The company wants to be able to use CFD (Computational Fluid Dynamics) modelling to explore design**changes that will result in optimization of the fan unit. The CFD analysis will predict the three-dimensional air**flow in the unit. Later, for the optimization process, the geometry and fan parameters can be changed and the**resulting performance will be predicted in detail by the software. This capability will yield economic benefits**for Price Industries by shortening the design cycle and making the company more competitive in this product**category. The first step, however, is to obtain a reliable CFD model for the current fan unit configuration.**The objectives of this project are to develop a steady-state CFD model of the fan unit using commercial**software and to validate that model. Model parameters will be varied and comparisons with available in-house**experimental data will be performed.
