Hydrodynamic and mass transfer efficiency of ceramic foam packing applied to distillation. [PDF]

, 2009
In addition to a high void volume and specific area, solid foams possess other properties (low density, good thermal, mechanical, electrical, and acoustical behaviour) that make them attractive for applications such as heat exchangers and reformers ...

Is front crawl swimming performance affected by hydrodynamic drag in young swimmers? [PDF]

, 2010
Swimming performance is affected by several factors including the hydrodynamic drag. Hydrodynamic drag is the force that a swimmer has to overcome in order to maintain his movement through water and is highly dependent on swimming technique. PURPOSE:
