N experiment combining flow visualization and temperature measurement is carried out in the present study to investigate the possible presence of new inertia-driven vortex rolls and some unique characteristics of the time-dependent mixed convective vortex flow resulting from a high speed round air jet impinging onto a heated horizontal circular disk in a vertical cylindrical chamber.

First, UWPBL model(The University of Washington Planetary Boundary Layer Model) is used to retrieve typhoon's sea level pressure from sea surface winds data of SeaWinds which aboard on QuikSCAT and these strength results are analyzed. Then the variational method is applied to decompose the sea surface winds field into two parts: the vortex and irrotational environmental flow field, the UWPBL model is used again to retrieve ShanShan and YaGi typhoons' sea level pressure from the vortex flow field, the results of typhoon's central positions are analyzed by comparing the results with the results of direct retrieving, NCEP's data and typhoon annual reports. It turns out that the accuracy of the typhoon's sea level pressure central position has been obviously improved, This method offers a new idea for the study of typhoon from microwave scatterometer data.

本文首先利用QuikSCAT散射计获取的海面风场资料，利用华盛顿大学行星边界层模式对台风海平面气压场进行反演，并对其强度进行了分析；然后对获取的海面风场，采用变分方法对风场进行分解，分解出无旋和有旋风场，对分解出的有旋风场，再利用UWPBL模式对珊珊和魔羯台风的海平面气压场进行了反演，对所得结果与通常直接反演、NCEP海平面气压场及台风报文资料进行一一对比，结果表明：新的反演定位的方法对台风海平面气压场中心气压的定位精度有了大幅度的提高，此种定位的方法为散射计资料在台风中的实际应用开辟了一条新的思路。

It is available to carry out numerical simulation and fluid dynamic analysis further. Based on Frozen-Rotor Approach and Rotor-Stator Approach, the numerical simulation was carried out in the centrifugal pump and the numerical results showed that the flow in the impeller and volute of centrifugal pump is periodically unsteady. Due to the interaction between impeller and volute the flow is characterized by pressure fluctuations and it is the strongest at impeller outlet and at the vicinity of the tongue. The unsteady pressure fluctuations are also one of the most important reasons to induce vibration and noise. Secondly, the flow field of the volute is characteristic of the vortex flow, and the vortex flow presents very complicated developing process which is creating, increasing and dissipating every now and then. All these lead to very large flow loss in the volute.

采用Frozen-Rotor冻结转子模式和Rotor-Stator滑移界面模式系统开展了不同工况下离心泵内叶轮与蜗壳耦合的定常和非定常流动研究，结果表明由于叶轮与蜗壳的干扰蜗壳进口周向流动的不均匀性是非常强烈的，特别是叶轮与蜗舌间的相互干扰最为强烈，一直影响到叶轮进口和蜗壳扩散管出口的流场；在蜗壳内整个流动是以旋涡形式向出口推进的，并随着包角的变化旋涡表现出十分复杂的产生、发展和耗散的演化过程，导致蜗壳内较大的流动损失。
