(Department of Theoretical and Applied Mechanics (UIUC), 200504)We develop a complete set of equations governing the evolution of a sharp interface separating two fluid phases undergoing transformation. In addition to the conventional balances for mass, linear momentum, and energy these ...

(American Institute of Physics, 200101)When a solid sphere impacts on a deep layer of granular medium, it generates an ejecta sheet and a transient axisymmetric crater. The gravitydriven radial collapse of this crater generates a pressure spike, as the cavity ...

(Department of Theoretical and Applied Mechanics (UIUC), 200005)Worthington jets are a familiar sight in light rain upon puddles and ponds. These narrow vertical jets are formed by the radial collapse of the liquid "craters" produced by the impacting rain drops. Such jets can also be ...

(Department of Theoretical and Applied Mechanics (UIUC), 200207)Working with the context of a theory proposed recently by Fried et al. (2001), we consider a onedimensional problem involving granular mixture of K > 2 discrete sizes bounded below by an impermeable base, above by an ...

(2003)Beamlike structural elements with length much greater than the characteristic length of the crosssection are vulnerable to large forces induced either by constrained thermal expansions and contractions, or by the weights ...

(1983)A twodimensional mean circulation was set up along with turbulent thermal convection in a slightly inclined layer of water, heated from below and insulated at top and sides. Mean flow and turbulent moments were measured ...

(1997)Unfortunately, but not surprisingly, there arises a closure difficulty: the reduced set of physically admissible measures is still large. In this thesis a particular subclass of admissible measures is studied using the ...

(Department of Theoretical and Applied Mechanics (UIUC), 200512)Microgravity conditions pose unique challenges for fluid handling and heat transfer applications. By controlling (curtailing or augmenting) the buoyant and thermocapillary convection, the latter being the dominant convective ...

(Department of Theoretical and Applied Mechanics (UIUC), 200402)We present an accurate and fast wave tracking method that uses parametric representations of tracked fronts, combined with modifications of levelset methods that use narrow bands. Our strategy generages accurate computation ...

(Department of Theoretical and Applied Mechanics (UIUC), 200302)Microencapsulated healing agents that possess adequate strength, long shelflife, and excellent bonding to the host material are required for selfhealing materials. Ureaformaldehyde microcapsules containing dicyclopentadiene ...

(American Institute of Physics, 2006)In a nematic elastomer the deformation of the polymer network chains is coupled to the orientational order of the mesogenic groups. Statistical arguments have derived the socalled neoclassical free energy that models this ...

(Department of Theoretical and Applied Mechanics (UIUC), 200508)In a nematic elastomer the deformation of the polymer network chains is coupled to the orientational order of the mesogenic groups. Here we use the neoclassical model for this coupling supplemented by the usual Frank ...
