Review of fluid flow and convective heat transfer within rotating disk cavities with impinging jet

摘要

Fluid flow and convective heat transfer in rotor-stator configurations, whichare of great importance in different engineering applications, are treated indetails in this review. The review focuses on convective heat transfer inpredominantly outward air flow in the rotor-stator geometries with and withoutimpinging jets and incorporates two main parts, namely,experimental/theoretical methodologies and geometries/results. Experimentalmethodologies include naphthalene sublimation techniques, steady state (thinlayer) and transient (thermochromic liquid crystals) thermal measurements,thermocouples and infra-red cameras, hot-wire anemometry, laser Doppler andparticle image velocimetry, laser plane and smoke generator. Theoreticalapproaches incorporate modern CFD computational tools (DNS, LES, RANS etc).Geometries and results part being mentioned starting from simple to complexelucidates cases of a free rotating disk, a single disk in the crossflow,single jets impinging onto stationary and rotating disk, rotor-stator systemswithout and with impinging single jets, as well as multiple jets. Conclusionsto the review outline perspectives of the further extension of theinvestigations of different kinds of the rotor-stator systems and theirapplications in engineering practice.
