As we know, the garment varied between exaggeration and nature shape, as the supporting part of the tops, which also changed from emphasis to nature. Opening out qualitative and quantitative study on exaggerative shoulder shape was the hot point in the research field of garment construction, which had strong realistic significance. So depending on the warped shoulder shape, this paper selected the warped amount, which was the important effecting factors to the upturned shoulder shape, as research object. Through making up series of sample garments and subjective evaluation system, this article analyzed the effecting of the varying upturned amount to the warped shoulder shape, and got the best data of the upturned amount, which could offer some theoretical supporting to optimize the upturned shoulder shape

Air-jet pump as the pneumatic source of a vehicle-mounted vacuum toilet provides the vacuum to pump the fecal sewage out of toilet bowl via the compressed air passing through the pump under certain pressure. In this study, Computational Fluid Dynamics (CFD) technique is employed to investigate the effects of three important air-jet pump geometry parameters: the primary Nozzle Exit Position (NXP), the constant-area section length (L1) and the diffuser diverging angle (θ), on its performance. A CFD model is firstly established according to 1D analytical method, and then used to create 135 different air-jet pump geometries and tested under different operating conditions. The significance of this study is that these findings can be used to guide the adjustment of NXP, L1 and θ to obtain the best air-jet pump performance when the operating conditions are different.
