Finite-volume solution of the compressible boundary-layer equations

Error Estimates on the Approximate Finite Volume Solution of Convection Diffusion Equations with General Boundary Conditions

We study here the convergence of a nite volume scheme for a diiusion-convection equation on an open bounded set of IR d (d = 2 or 3) for which we consider Dirichlet, Neumann or Robin boundary conditions. We consider unstructured meshes which include Vorono or triangular meshes; we use for the diiusion term an \s points" (where s is the number of sides of each cell) nite volume scheme and for th...

an enhanced finite- volume method for the solution of compressible flows

an enhamced scheme is introduced for the solution of two dimensional umsteady euler equations. the finite- volume method of jameson et al. is modified by devicing a pnessune sensor in cell flux calculations. then the discretized gorerning equations ane relaxed in time until na steady state is reached. an appropriate model for the artificial dissipation was also employed. several tests wene cond...

existence and approximate $l^{p}$ and continuous solution of nonlinear integral equations of the hammerstein and volterra types

بسیاری از پدیده ها در جهان ما اساساً غیرخطی هستند، و توسط معادلات غیرخطی ‎‏بیان شد‎‎‏ه اند. از آنجا که ظهور کامپیوترهای رقمی با عملکرد بالا، حل مسایل خطی را آسان تر می کند. با این حال، به طور کلی به دست آوردن جوابهای دقیق از مسایل غیرخطی دشوار است. روش عددی، به طور کلی محاسبه پیچیده مسایل غیرخطی را اداره می کند. با این حال، دادن نقاط به یک منحنی و به دست آوردن منحنی کامل که اغلب پرهزینه و ...

Unstructured mesh methods for the solution of the unsteady compressible flow equations with moving boundary components.

A review of a procedure for the simulation of time-dependent, inviscid and turbulent viscous, compressible flows involving geometries that change in time is presented. The adopted discretization technique employs unstructured meshes and both explicit and implicit time-stepping schemes. A dual time-stepping procedure and an ALE formulation enable flows involving moving boundary components to be ...
