Fluid1
Conduction as heat transfer takes place if there is a temperature gradient in a solid or stationary fluid medium. (engineeringtoolbox.com)
Occurs3
The mode of conduction into the wall depends on whether dropwise condensation or filmwise condensation occurs, as will be discussed below. (thermalfluidscentral.org)
In short, when filmwise condensation occurs uniformly along the surface, the heat flux can simply be found from a straight application of Fourier's Law of conduction into a solid. (thermalfluidscentral.org)
However, if dropwise condensation occurs, conduction into the wall is constricted around the individual droplets and cannot occur uniformly over the solid wall. (thermalfluidscentral.org)
Oven2
Students experiment with heat transfer through conduction by how well the oven is insulated and radiation by how well it absorbs solar radiation. (teachengineering.org)
Linda suggests placing the oven on a base of fire bricks - these retain heat and release it inside the oven through radiation and the convective heating of air. (communitygarden.org.au)
Temperatures2
Calm and sunny days on a snow-covered (reflective) landscape with moderating temperatures, can create an environment conducive to hyperthermia (overheating). (iditarod.com)
Heat loss through conduction is usually relatively small (3%), but will become more significant as ambient temperatures drop and is most critical in cases of water immersion. (iditarod.com)
Place2
Cooling of the air above the surface must take place by conduction and radiation, and these are slow processes. (nwcg.gov)
If the gas emission takes place under these conditions, the referred convective air flows dilute the contaminating gas and elevate it several meters above the soil, thus avoiding the odour perception at near populated areas. (frostprotection.com)

Resistance2
However, if the vapor is superheated, this mixing process is severely limited, and the resistance of the vapor phase would have to be considered in the form of conduction through vapor. (thermalfluidscentral.org)
Furthermore, other materials cannot be substituted at will when covering the fuse, because the fuse box's material is completely considered for insulation and high-temperature resistance, and covering the fuse with other materials at will result in a fire hazard. (silan-icsouls.com)
