foiling and basting - genuineideas

Heat conduction from foil through air to meat is much weaker. Steam does not immediately form inside a foil pack- the cooler food lowers the internal air temperature, and evaporative cooling slows the heating process. Wrapping in foil braises the food for hours, until the liquid nears the boiling point. Again, most of the time, it is not steaming.

Both the shiny and the diffuse aluminum foil sides will reflect energy back. The sides should not make a difference on food on a counter. To really insulate there should be a non conducting side on the outside ( like a space blanket), as the foil reaching the hot temperature of the container will radiate away heat according to black body radiation.

Q & A: aluminum foil heat conduction - Department of Physics

Since the foil wraps around the food, the main directions it conducts heat don't matter. The heat flow is at right angles to the foil surface. The shielding of the radiation by the foil should help reduce the heat flow. If, however, the foil sits on some cool material that's a good thermal conductor, then it could provide a path for heat to ...

"Thin" is a relative term, but let's assume we're talking a foil that's 0.01 to 0.02 mm thick (i.e., kitchen aluminum foil). Let's also assume that our foil is a soft alloy -- i.e. nearly pure aluminum or iron. If I take a piece of kitchen foil and I bend it with my hands, the bend radius is likely going to be no less than 5mm.

LIMITING PHYSICS: Stalling: At angles of attack below around ten to fifteen degrees, the lift increases with an increasing angle. However, if the angle of attack is too large, stalling takes place. Stalling occurs when the lift decreases, sometimes very suddenly. The phenomena responsible for stalling is flow separation (see Figure 9).
