Magnetic gravity compensation
Vadim Nikolayev, D. Chatain, D. Beysens +1
Magnetic gravity compensation in fluids is increasingly popular as a means to achieve low-gravity forphysical and life sciences studies. We explain the basics of the magnetic gravi…
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…
Experimental Evidence of the Vapor Recoil Mechanism in the Boiling Crisis
Vadim Nikolayev, D Chatain, Y Garrabos +1
Boiling crisis experiments are carried out in the vicinity of the liquid-gas critical point of H2. A magnetic gravity compensation setup is used to enable nucleate boiling at near…
Quench cooling under reduced gravity
D. Chatain, C. Mariette, V. S. Nikolayev +1
We report the quench cooling experiments performed with liquid O2 under different levels of gravity simulated with the magnetic gravity compensation. A copper disk is quenched from…
Is CHF triggered by the vapor recoil effect?
Vadim S. Nikolayev, D. Beysens, D. Chatain
This paper deals with the triggering mechanism of the boiling crisis, a transition from nucleate to film boiling. We observe the boiling crisis in pool saturated boiling experiment…
