Conjugate heat transfer analysis of leading edge and downstream mist–air film cooling on turbine vane

Stability analysis of partitioned methods for predicting conjugate heat transfer

“…It is prevalent in engineering sciences (e.g. [1,2]) and was first formulated by Perelman [3]. The correct prediction of conjugate heat transfer requires to simultaneously solve for the heat conduction in the solid and the Navier-Stokes equations in the fluid, where at the interface between both domains the temperature and heat flux have to be treated as unknowns and are found during the solution of the coupled problem.…”

A thermal‐structure coupled optimization study of lithium‐ion battery modules with mist cooling

“…Evaporative cooling was adopted for its feature of dissipating high heat flux at a relatively lower expense. 25,26 Coolant droplets dissipate excessive heat from the surfaces to reach a desired cooling effect through evaporation. Unlike principal other cooling methods that need extra equipment (pump, cooling plates, or heat exchanger), evaporation is a natural process in the environment, which requires the minimum energy consumption during the operation process.…”

Novel thermal management system using mist cooling for lithium-ion battery packs

“…Evaporative cooling is an emerging cooling technology adopted in the current thermal management system owing to its ability to dissipate high heat flux at reasonable cost [21][22]. Coolant droplets absorb excess heat from the heated surface to provide cooling via evaporation.…”

“…Cooling enhancement of 20 % is achieved when 2 % wt of mist is injected to the air stream. Furthermore, mist-air film cooling is effective in reducing the vane-wall temperature in a gas turbine by 20 K to 48 K with addition of 1 % to 3 % mist ratio [25].…”
