Natural convection effects in the insulation layers of spherical storage tanks are studied for
different cryogenic fluids and tank sizes or curvatures. The non-vacuum-based insulation …

A numerical simulation of natural convection in a horizontal porous annulus with an internal
wavy surface has been carried out. Governing equations include the heat equation and the …

The influence of gravitational modulation on natural convection in a horizontal porous
annulus is investigated in this paper. The mathematical model describing the phenomenon …

The existing cryogenic hydrogen storage technologies utilize vacuum-based insulation
systems, leading to significantly high maintainance cost and potentially huge losses …

Many rotor assemblies of industrial turbomachines are supported by oil-lubricated bearings.
It is well known that the operation safety of these machines is highly dependent on rotors …

This paper reports on the natural convection within a very narrow horizontal annular cavity
filled with a porous medium saturated by a binary fluid. The main objective of this study is the …

This chapter investigates the convective instability in a horizontal porous annulus subjected
to quasi-periodic (QP) gravitational modulation having two incommensurate frequencies …

This paper investigates the thermal instability in a horizontal porous annulus with an
external wavy wall. The porous matrix is supposed to be filled by an incompressible fluid …

In the current study, energy analyses were performed to enhance the characteristics and
forced convection performance in the horizontal annular in the case of the presence of …

In the current study, to enhance the characteristics and forced convection performance in the
