When an obstacle closes to a wall, the boundary layer on the wall and flow around the obstacle interact and form a complex flow field. The resulting flow is highly mixed and turbulent. Turbulence models are not modified to handle such a flow field...

Scaled boundary finite element method (SBFEM) has proved its abilities in problems with singularities successfully. In this work, the coupling of SBFEM and a hybrid optimization algorithm is employed to determine unknown heat flux in the transient...

In this paper, we present an inverse analysis to estimate the

thermal boundary conditions over a two-dimensional radiant

enclosure from the knowledge of the measured temperatures for

some points on a solid object within...

The classical Permian-Triassic (P-Tr) boundary sections in the vicinity of Julfa (NW Iran) have high potential for the study of the end-Paleozoic extinction event. The lithostratigraphic record of the P-Tr boundary beds in the Julfa area is rather...

In this paper numerical study of cavity over hydrofoils is considered by using boundary element method based on potential flow. For this purpose hydrofoil and cavity surface are approximated by panels. Then sources and doublets are distributed over...

In this paper, the variational iteration method is applied to solve mth-order boundary value problems. Using this method we only need to apply an iteration to obtain solutions of remarkable accuracy. By giving 3 examples and by comparing...

An optimization technique is applied to design of heat transfer systems in which the natural convection is important. The inverse methodology

is employed to estimate the unknown strengths of heaters on the heater ...
