One of the areas of my research interest is abrasive wear induced by the flow of concentrated solid-laden liquid, i.e., the material wear caused by particle flowing past a surface as slurry or suspension. This question has been motivated by a desire to understand the change in the geometry of the perforations in the well stimulation technique of hydraulic fracturing in the petroleum industries. Wear due to slurry flow is also seen in pipelining, a topic of interest for coal slurry transport. Abrasive Flow Machining (AFM) is also one of the applications involving abrasive slurry wear.
My PhD thesis lied at the intersection of fluid mechanics and biology. The previous observations regarding the remarkable similarity between a human skiing on the snow powder and the motion of red cell passing through tightly fitting capillaries showed that the dimensionless permeability parameter α for a gliding motion of a red cell moving over the endothelial glycocalyx layer (EGL) and a human snowboarding on compressed powder is roughly 100, although they differ in mass by 15 orders of magnitude. The biggest difference between them is the huge loss of excess pore pressure from the lateral edges of the ski, thus the pressure and lift force decrease as (W/L)2 for large α where W is the width of the planning surface and L is the length. For a skier less than 40% of the lift comes from the air transiently trapped beneath ski due to this loss of pressure.
This investigation, motivated the study of the generation of lift force in random, soft porous media. A lubrication theory for random, highly compressible porous media was developed and was shown that a huge lift force can be generated in random fibers that can be used in several applications such as slider bearings or commercial transportations, however, for its novelty we applied this enhanced lift force to design a new train track.
Using an asymptotic analysis for large values of the permeability parameter, α=H/√Kp, where H is the porous layer thickness and Kp the Darcy permeability, the possibility to support a 70 metric ton jet train carrying 200 passengers on a confined porous material where its Kp is approximately 5 x 10-9 m2 was examined. This value of Kp can be satisfied by a random fiber matrix with a fiber radius of 5 µm and a void fraction of 0.995. Using jet engines of 10,000 lbf thrust, about 1/5 that of a 200 passenger jet aircraft, one is able to obtain a cruising velocity approaching 700 km/hr. This would allow for huge fuel savings, especially on short flights where much of the energy expenditure is used to climb to altitude and overcoming lift induced drag.
