Physics and modeling of liquid films in pulsating heat pipes
Xiaolong Zhang, Vadim Nikolayev
The present study reports a novel physical model for simulating Pulsating Heat Pipes (PHP). Their high heat performance is due to the phase change over thin liquid films. The simul…
Microlayer in nucleate boiling seen as Landau-Levich film with dewetting and evaporation
Cassiano Tecchio, Xiaolong Zhang, Benjamin Cariteau +6
Both experimental and theoretical studies on the microscale and fast physical phenomena occurring during the growth of vapor bubbles in nucleate pool boiling are reported. The focu…
A Dynamic Film Model of the Pulsating Heat Pipe
Vadim Nikolayev
This article deals with the numerical modeling of the pulsating heat pipe (PHP) and is based on the film evaporation/condensation model recently applied to the single-bubble PHP (D…
Liquid film dynamics with immobile contact line during meniscus oscillation
Xiaolong Zhang, Vadim Nikolayev
This paper presents a theoretical analysis of the liquid film dynamics during the oscillation of a meniscus between a liquid and its vapour in a cylindrical capillary. By using the…
Bubble spreading during the boiling crisis: modelling and experimenting in microgravity
Vadim Nikolayev, D Beysens, Y Garrabos +2
Boiling is a very efficient way to transfer heat from a heater to the liquid carrier. We discuss the boiling crisis, a transition between two regimes of boiling: nucleate and film…
Growth of a dry spot under a vapor bubble at high heat flux and high pressure
Vadim Nikolayev, Daniel Beysens, G. -L. Lagier +1
We report a 2D modeling of the thermal diffusion-controlled growth of a vapor bubble attached to a heating surface during saturated boiling. The heat conduction problem is solved i…
