Mixed convection of nanofluid at the lower stagnation point of a horizontal circular cylinder: Brinkman–viscoelastic

Researchers have formulated the Brinkman–viscoelastic model to study the convective heat transfer of viscoelastic fluids traversing porous media recently.  Nevertheless, they did not employ nanofluids.  Currently, scientists and researchers are employing nanofluids and hybrid nanofluids in their studies, products, and technologies due to their ability to enhance the transfer of heat.  Therefore, the aim of this research is to study the heat transfer of a viscoelastic fluid with nanoparticles as it moves over a horizontal circular cylinder in a saturated porous region at

Mathematical modeling of elastic disturbance propagation in a structure containing a porous layer saturated with gas and water

A horizontally layered elastic structure containing a homogeneous porous layer saturated partly with gas and partly with water is considered. The paper is aimed at studying of interaction of elastic waves, caused by local pulse source, with the structure. The boundary-value problem describing the wave dynamics of the structure is formulated. A mathematical model describing distributions of the gas and water in a pore space of the porous layer depending of the amount of the gas accumulated in the layer is developed. The problem is solved with the use of Fourier transform.
