Mechanisms Of Boiling In Microchannels: Critical Assessment

John Richard Thome, Lorenzo Consolini

Numerous characteristic trends and effects have been observed in published studies on two-phase micro-channel boiling heat transfer. While macro-scale flow boiling heat transfer may be decomposed into nucleate and convective boiling contributions, at the m ...

Open-loop control of compressible afterbody flows using adjoint methods

Philippe Meliga

The flow past an axisymmetric body is generically unstable to a steady and a time-periodic global instability, the latter being thought to lead the low-frequency unsteadiness of the wake even at larger Reynolds numbers. The present paper examines how the g ...

Algebraic turbulence modeling in adiabatic gas–liquid annular two-phase flow

John Richard Thome, Andrea Cioncolini

The study considers algebraic turbulence modeling in adiabatic gas-liquid annular two-phase flow. After reviewing the existing literature, two new algebraic turbulence models are proposed for both the liquid film and the droplet laden gas core of annular t ...

INFLUENCE OF THE SATURATION TEMPERATURE ON THE HEAT TRANSFER COEFFICIENT FOR FLOW BOILING INSIDE HORIZONTAL SMOOTH TUBES

John Richard Thome, Ricardo Lima

This article presents experimental results of heat transfer from two different studies [1, 2] for horizontal flow boiling inside smooth copper tubes with different refrigerants. The main goal of this study was to verify the influence of the saturation temp ...

Convective boiling heat transfer in a single micro-channel

Lorenzo Consolini

The current industrial need for compact high heat density cooling devices has conveyed an increasing interest on convective boiling in micro-channels. Although there is general agreement that these systems may be able to dissipate potentially very high hea ...

Characteristic lengths affecting evaporative drying of porous media

Dani Or

Evaporation from porous media involves mass and energy transport including phase change, vapor diffusion, and liquid flow, resulting in complex displacement patterns affecting drying rates. Force balance considering media properties yields characteristic l ...

Turbulent transport in the TCV SOL

Jonathan Graves, Richard Pitts, Jan Horacek

From probe measurements in the far SOL of TCV it is demonstrated that while the particle density profile becomes increasingly broader with increasing line averaged density, the radial variation of the fluctuation statistics remains the same. Excellent agre ...

Large Eddy Simulation of turbulent compressible flow in heated curved square duct

Characteristics of turbulent flow and heat transfers which develop in a heated duct are studied through Large Eddy Simulation (LES) technics . Cooling channels of rocket engines constitute one of the industrial applications. We here consider a simplified g ...

Experimental two-phase fluid flow in microchannels

Rémi Revellin

Micro or mini heat spreaders are used in the interest of providing higher cooling capability for microtechnologies. Heat spreaders using micro or mini channels are not yet well studied, for this the fundamentals of two-phase heat transfer in microchannels ...
