As opposed to a forced convection flow where external means are used to provide the flow, the free-convection flow field is a self-sustained flow driven by the presence of a temperature gradient.

Modeling of natural convection
2016 2nd International Conference on Industrial Engineering, Applications and Manufacturing (ICIEAM), 2016Numerical simulation with ANSYS Fluent, Code Saturne and OpenFOAM is compared in terms of the problem of natural convection in enclosed volume of air in the presence of a heating element. A comparative analysis of software on the basis of three turbulence models (k-e, SST and WALE) is conducted. The results adequacy is assessed.

Natural convection in droplet evaporation
Physical Review E, 1996Although droplet evaporation is widely assumed to be a diffusion process, our results show that when a droplet evaporates sufficiently fast it exhibits a vigorous interior flow. This flow is driven by surface tension gradients. The typical interior flow field behavior is shown as well as measurements of the droplet surface area and volume as it ...

Natural convection in a heated annulus
International Journal of Heat and Mass Transfer, 1993Natural convection in a heated vertical concentric annulus is studied. A constant heat-flux is applied to the inner cylinder and the outer cylinder is insulated. Under these conditions, the mean temperature of the fluid increases linearly while, at the same time, heat diffuses from the heated surface into the fluid, resulting in a temperature ...

Aquifers are being used more and more as heat reservoirs. Thermopumps provide energy for heating and, in the case of solar installations, the energy is stored in groundwater during summer to be used in winter. But groundwater has to be protected against the excessively high temperatures which modify water quality, and against chemical pollutants ...

Stability of Transient Natural Convection
The Physics of Fluids, 1969A theoretical analysis was carried out to determine the stability properties of unsteady natural convection. In this analysis a perturbation technique was used in conjunction with a special type unsteady base flow for transient natural convection between two infinite parallel vertical plates.
