شبیه‌سازی انتشار امواج گاوسی تخت شده در سیستم‌های اپتیکی ABCD با روش تبدیل پیرا محوری

In this paper, propagation of flattend Gaussian beam in optical media is simulated by split step fourier method, ABCD matrix method, and paraxial group method, and results are compared. For this purpose, at first, flattend Gaussian beam, strongly nonlocal nonlinear media and investigation methods of propagation of optical beams are introduced. Then, propagation of flattend Gaussian beam in free...

MHD Jeffrey NanoFluids Flow Over a Stretching Sheet Through a Porous Medium in Presence of Nonlinear Thermal Radiation and Heat Generation/Absorption

In this article, a numerical investigation of magnetohydrodynamic non-Newtonian nanofluid flow on a stretching sheet through an isotropic porous medium. The effects of both non-linear thermal radiation and heat generation/absorption were studied on distributions of velocity, temperature and concentration. On the other side, the governing partial differential equations have been transformed by u...

Free convective heat and mass transfer of magnetic bio-convective flow caused by a rotating cone and plate in the presence of nonlinear thermal radiation and cross diffusion

This article explores the heat and mass transfer behaviour of magnetohydrodynamic free convective flow past a permeable vertical rotating cone and a plate filled with gyrotactic microorganisms in the presence of nonlinear thermal radiation, thermo diffusion and diffusion thermo effects. We presented dual solutions for the flow over a rotating cone and a rotating flat plate cases. Similarity var...

Propagation of Waves at an Interface of Heat Conducting Elastic Solid and Micropolar Fluid Media

The present investigation is concerned with the reflection and transmission coefficients of plane waves at the interface of generalized thermoelastic solid half space and heat conducting micropolar fluid half- space. The amplitude ratios of various reflected and transmitted waves with various angle of incidence have been computed numerically and depicted graphically. Micropolarity and thermal r...
