A review on heat transfer enhancement with turbulators

AIP Conference Proceedings, 2018
For the purpose of saving energy and material, it is important to make heat transfer more effective. The heat exchange improvement approach is generally used in applications which are dealing with heat transfer. These approaches are classified into two types i.e. active and passive.

Heat Transfer in Drop-Laden Turbulent Flows

Volume 1: Fluid Applications and Systems (FASTC); Fluid Measurement and Instrumentation (FMITC); Fluid Mechanics (FMTC); Multiphase Flow (MFTC)
Abstract We study the heat transfer process in a multiphase turbulent system composed by a swarm of large and deformable drops and a continuous carrier phase. For a shear Reynolds number of Re = 300 and a constant drops volume fraction of Θ = 5.4%, we perform a campaign of direct numerical simulations (DNS) of turbulence coupled with a ...

On nonquasineutrality and turbulent heat transfer in a tokamak

Journal of Experimental and Theoretical Physics Letters, 1998
A new approach is proposed for describing a steady turbulent state formed far from thermodynamic equilibrium in the plasma column of a tokamak as a result of the development of microinstabilities. A fundamental feature of such a highly nonequilibrium plasma is its nonquasineutrality, i.e., the plasma properties are largely determined by electric fields

The influence of coking on heat transfer in turbulent reacting flow of supercritical hydrocarbon fuels

, 2019
Significant influence from coking (aggregation and formation of a non-desirable carbonaceous porous layer on a solid metal surface) on the heat transfer in a cooling system of hypersonic aircraft with hydrocarbon fuel as the coolant is observed.

Heat transfer in turbulent falling films

Chemical Engineering & Technology, 1995
AbstractIn condensers with high condensation rates or in falling film evaporators the falling film at the vertical tube wall shows a turbulent flow pattern. For optimal dimensioning of these apparatuses the knowledge and the description of the heat transfer in this turbulent falling film is necessary.
