Critical Heat Flux under Flow Oscillation in a Natural Circulation Loop of Liquid Nitrogen.

Chaotic flow in a 2D natural convection loop with heat flux boundaries

This computational study investigates the nonlinear dynamics of unstable convection in a 2D thermal convection loop (i.e., thermosyphon) with heat flux boundary conditions. The lower half of the thermosyphon is subjected to a positive heat flux into the system while the upper half is cooled by an equal-butopposite heat flux out of the system. Water is employed as the working fluid with fully te...

Experimental Study on the Effect of Magnetic Field on Critical Heat Flux of Ferrofluid Flow Boiling in a Vertical Tube

In the present work, the critical heat flux measurements were performed for the subcooled flow boiling of pure water and magnetic nanofluids (i.e., water + 0.01 and 0.1 vol.% Fe‌‌3O4) in a vertical tube. The effect of applying an external magnetic field on the CHF variation was studied experimentally as well. The obtained results indicated that the subcooled flow boiling CHF in the vertical tub...

The Effect of Linear Change of Tube Diameter on Subcooled Flow Boiling and Critical Heat Flux

One of the major industry problems is the flow boiling, where reaching to the critical heat flux (CHF) condition can lead to a temperature jump and damage of the systems. In the present study, the effects of a uniform change in tube diameter on subcooled flow boiling and CHF was numerically investigated. The Euler-Euler model was used to investigate the relationship between the two liquid and v...

Critical Heat Flux in Subcooled Flow Boiling of Water

Critical heat flux enhancement by means of liquid subcooling and centrifugal force induced by flow curvature

Experiments are performed to assess the feasibility of cooling high flux heat sources flush mounted on the inner wall of a cylindrical vessel by a dielectric liquid flowing at high velocity parallel to the vessel wall. Fluid motion is induced by rotating a stirrer having radial blades about the axis of the vessel. The study focusses on examining critical heat flux (CHF) enhancement attributed t...
