Where to begin learning about the effect of “crud” deposits on surface temperature, dry-out and pressure drop, with forced convection boiling of water at 69 bar in an annular test section? A good place to begin is the study: “An investigation into the effect of ‘crud’ deposits on surface temperature, dry-out and pressure drop, with […]

Running on water: On the earth and on the moon
It would be even better on the moon. Yes, here on earth you can run atop a pool of water-mixed-with-cornstarch, as people are doing in this video: But you could also run atop a pool of pure water—if you and that water were somewhere that has weaker gravity. The moon is one such place. An […]
Physics: Claiming control of the coffee-stain effect
From Paris comes news of a new class of surfaces that (among other things) offer better control of coffee stains. Details are in the study: “Slippery pre-suffused surfaces,” A. Lafuma and David Quéré [pictured here], EPL (Europhysics Letters), vol. 96, no. 5, 2011. The authors, at Laboratoire de Physique et Mécanique des Milieux Hétérogènes, CNRS, […]
