Free convection on a refrigerator’s condenser

On the Capacity of a Condenser

When are solar refrigerators less costly than on-grid refrigerators: A simulation modeling study☆

BACKGROUND Gavi recommends solar refrigerators for vaccine storage in areas with less than eight hours of electricity per day, and WHO guidelines are more conservative. The question remains: Can solar refrigerators provide value where electrical outages are less frequent? METHODS Using a HERMES-generated computational model of the Mozambique routine immunization supply chain, we simulated the...

On a nonlinear system of PDE’s arising in free convection

In this paper, we consider a model problem introduced in [2], and derived from a coupled system of partial differential equation arising in the study of free convection about a vertical flat plate embedded in a porous medium. In [2], some existence result has been obtained under very constraining hypothesis. Here, we come back to the weak formulation of this problem, and prove that there is one...

Effects of Chemical Reaction and Pressure Work on Free Convection over a Stretching Cone Embedded in a Porous Medium

Unsteady Free Convection from a Sphere in a Porous Medium with Variable Surface Temperature

In this paper a transient free convection flow around a sphere with variable surface temperature and embedded in a porous medium has been considered. The temperature of the sphere is suddenly raised and subsequently maintained at values that varies with position on surface. The method of asymptotic expansions is applied for small Rayleigh numbers and then a finite-difference scheme is used to s...
