  1. Based on the review, the fluid flow and heat transfer in the curved circular and rectangular pipes have been researched by employing perturbation method and numerical simulation with a physical model under the rotational orthogonal curvilinear coordinate in a rotating curvilinear pipe with multi - parameters. we firstly analyzed the fully developed fluid flow and heat transfer, mixed convection heat transfer, the development of flow and heat transfer in the inlet in different cross section ( circular, elliptical, annular and rectangular crossection ). the variations of the secondary flow, axial velocity, distribution of temperature, the friction force on the wall, the ratio of friction factor as well as the nusselt number with different dimensionless parameters had been examined in detailed

    本文在總結和分析了一個世紀以來有關曲線道流和換熱特性的研究成果的基礎上,以旋正交曲線坐標系統下的多參數旋螺旋道中的對流熱為物理模型,通過攝方法和有限體積法,首次對各種截面(圓截面、橢圓截面、環形截面、形截面)旋曲線道內充分發展流的流結構和熱特性(包括耦合對流熱特性)以及旋曲線道開口段發展流的流結構和換熱特性進行了系統的數值模擬和理論分析,詳細討論了各種無量綱參數對道內向速度分佈、二次流結構、溫度分佈、壁面摩擦力、摩擦系數比以及道nusselt數的影響,獲得了若干創新性成果。
