• Critical heat flux — describes the thermal limit of a phenomenon where a phase change occurs during heating (such as bubbles forming on a metal surface used to heat water), which suddenly decreases the efficiency of heat transfer, thus causing localised overheating… …   Wikipedia

• Heat transfer — is a discipline of thermal engineering that concerns the exchange of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase change …   Wikipedia

• Heat flux — or thermal flux is a flow of energy per unit of area per unit of time. In SI units, it is measured in [W·m 2] . It has both a direction and a magnitude so it is a vectorial quantity. To define the heat flux at a certain point in space, one takes… …   Wikipedia

• Critical exponent — Critical exponents describe the behaviour of physical quantities near continuous phase transitions. It is believed, though not proven, that they are universal, i.e. they do not depend on the details of the physical system, but only on the… …   Wikipedia

• Heat shock protein — Heat shock proteins (HSP) are a group of proteins whose expression is increased when the cells are exposed to elevated temperatures or other stress. This increase in expression is transcriptionally regulated. This dramatic upregulation of the… …   Wikipedia

• Critical phenomena — In physics, critical phenomena is the collective name associated with the physics of critical points. Most of them stem from the divergence of the correlation length, but also the dynamics slows down. Critical phenomena include scaling relations… …   Wikipedia
