The application of mesh-free discrete element method (DEM) for modeling macroporous inverse opals is proposed. developed and implemented DEM-based strategy applied to analyze stiffness strength made pure silica coated with titania layers various thicknesses. Also, the influence porosity initial packing on properties material investigated. Simulation results have shown that due heterogeneous mac...

A novel simulation framework has been developed in this study for the direct numerical of aerodynamic breakup a vaporizing drop. The interfacial multiphase flow with phase change is resolved using consistent geometric volume-of-fluid method. bulk fluids are viscous and incompressible surface tension at interface. newly-developed methods have implemented Basilisk solver, which adaptive octree/qu...

Approximate eigenpairs (quasimodes) of axisymmetric thin elastic domains with laterally clamped boundary conditions (Lamé system) are determined by an asymptotic analysis as the thickness (2ε) tends to zero. The departing point is the Koiter shell model that we reduce by asymptotic analysis to a scalar model that depends on two parameters: the angular frequency k and the half-thickness ε. Optim...

In this study, the missile staging process by implementing a side-injected jet is simulated numerically. The problem is considered to be axisymmetric and the thin shear layer approximation of Navier-Stokes equations along with an algebraic turbulence model is used in a quasi-static form for the calculations. The free stream corresponds to a very high altitude flight condition with a Mach number...
