TL;DR: In this paper, a two-dimensional solution for unsteady natural convection is obtained, using the immersed boundary method (IBM) to model an inner circular cylinder based on the finite volume method for different Rayleigh numbers varying over the range of 103-106.

TL;DR: In this paper, the authors investigated the effect of the inner cylinder location in an enclosure and the buoyancy-induced convection on heat transfer and fluid flow, and the existence of local peaks of the Nusselt number along the surfaces of the cylinder and the enclosure was determined by the gap and the thermal plume governed by the conduction and the convection.

TL;DR: In this article, a comprehensive numerical study has been conducted to investigate three-dimensional, steady, conjugate heat transfer of natural convection and conduction in a vertical cubic enclosure within which a centered, cubic, heat-conducting body generates heat.

TL;DR: In this paper, potential heat exchanger designs for an aero gas turbine recuperator, intercooler, and cooling-air cooler are suggested based on results reported in previous studies.

TL;DR: The present study investigates the variation of static contact angle of a water droplet in equilibrium with a solid surface in the absence of a body force and the dynamic contact angles of water droplets moving on a solidsurface for different characteristic energies using the molecular dynamics simulation.
