Enhancing heat transfer in vortex generator-type multifunctional heat exchangers
Charbel Habchi,Serge Russeil,Daniel Bougeard,Jean-Luc Harion,Thierry Lemenand,Dominique Della Valle,Hassan Peerhossaini +6 more
TL;DR: In this article, the heat transfer in turbulent vortical flows is studied using threedimensional numerical simulations, where vortex generators are fixed at a certain distance from the tube wall and rows of small protrusions are inserted on the tube walls.

A review on single-phase convective heat transfer enhancement based on multi-longitudinal vortices in heat exchanger tubes
TL;DR: In this paper, a review on single-phase convective heat transfer enhancement based on multi-longitudinal vortices is carried out, and some new perspectives on the existing research gaps, challenging, and future research directions have been provided for the development of enhanced heat transfer techniques by generating multilevel vortex generators in heat exchanger tubes.

The theory of homogeneous turbulence
TL;DR: In this article, the kinematics of the field of homogeneous turbulence and the universal equilibrium theory of decay of the energy-containing eddies are discussed. But the authors focus on the dynamics of decay and not on the probability distribution of u(x).
Journal ArticleDOI
Fundamentals of the hydrodynamic mechanism of splitting in dispersion processes
TL;DR: In this paper, Taylor's experiments on the breakup of a drop in simple types of viscous flow, (b) breakup of an air stream, and (c) emulsification in a turbulent flow are studied.

Description of interaction processes in agitated liquid-liquid dispersions
TL;DR: In this paper, phenomenological models are proposed to describe drop breakup and coalescence in a turbulently agitated liquid-liquid dispersion, and the breakage and rate functions are developed and used to solve the general population balance equation describing drop interactions in a continuous flow vessel.

Advanced models of fuel droplet heating and evaporation
TL;DR: In this article, the effect of finite thermal conductivity and recirculation in droplets can be taken into account using the so-called parabolic model, which is a reasonable compromise between accuracy and CPU efficiency.

Breakage and coalescence models for drops in turbulent dispersions
TL;DR: In this article, two-step mechanisms are considered for both the breakage and coalescence models, and a probability density is proposed based on the energy requirements for the formation of daughter drops.
