Study on dry-out occurrence in inclined loop thermosyphon for CPU cooling

Application of a two-phase thermosyphon loop with minichannels and a minipump in computer cooling

This paper focuses on the computer cooling capacity using the thermosyphon loop with minichannels and minipump. The one-dimensional separate model of two-phase flow and heat transfer in a closed thermosyphon loop with minichannels and minipump has been used in calculations. The latest correlations for minichannels available in literature have been applied. This model is based on mass, momentum,...

CPU Cooling in Data Center Using a Thermosiphon Loop with Tapered Open Microchannel Manifold (OMM)

Diffusion Induced Chaos in a Closed Loop Thermosyphon

The dynamics of a closed loop thermosyphon are considered. The model assumes a prescribed heat flux along the loop wall and the contribution of axial diffusion. The well-posedness of the model which consists of a coupled ODE and PDE is shown for both the case with diffusion and without diffusion. Boundedness of solutions, the existence of an attractor, and an inertial manifold is proven, and an...

Monodisperse dry granular flows on inclined planes: role of roughness.

Recent studies have pointed out the importance of the basal friction on the dynamics of granular flows. We present experimental results on the influence of the roughness of the inclined plane on the dynamics of a monodisperse dry granular flow. We found experimentally that there exists a maximum of the friction for a given relative roughness. This maximum is shown to be independent of the slope...
