  2. Thermal contact conductance - Wikipedia

    en.wikipedia.org/wiki/Thermal_contact_conductance

    Fig. 1: Heat flow between two solids in contact and the temperature distribution. When two solid bodies come in contact, such as A and B in Figure 1, heat flows from the hotter body to the colder body. From experience, the temperature profile along the two bodies varies, approximately, as shown in the figure. A temperature drop is observed at ...

  3. Rate of heat flow - Wikipedia

    en.wikipedia.org/wiki/Rate_of_heat_flow

    The rate of heat flow is the amount of heat that is transferred per unit of time in some material, usually measured in watts (joules per second). Heat is the flow of thermal energy driven by thermal non-equilibrium, so the term 'heat flow' is a redundancy (i.e. a pleonasm). Heat must not be confused with stored thermal energy, and moving a hot ...

  4. Thermodynamic cycle - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_cycle

    Heat flows into the loop through the top isotherm and the left isochore, and some of this heat flows back out through the bottom isotherm and the right isochore, but most of the heat flow is through the pair of isotherms. This makes sense since all the work done by the cycle is done by the pair of isothermal processes, which are described by Q ...

  5. Heat flux - Wikipedia

    en.wikipedia.org/wiki/Heat_flux

    In physics and engineering, heat flux or thermal flux, sometimes also referred to as heat flux density [1], heat-flow density or heat-flow rate intensity, is a flow of energy per unit area per unit time. Its SI units are watts per square metre (W/m 2). It has both a direction and a magnitude, and so it is a vector quantity.

  6. Heat equation - Wikipedia

    en.wikipedia.org/wiki/Heat_equation

    where is the thermal conductivity of the material, = (,) is the temperature, and = (,) is a vector field that represents the magnitude and direction of the heat flow at the point of space and time . If the medium is a thin rod of uniform section and material, the position x is a single coordinate and the heat flow q = q ( t , x ) {\displaystyle ...

    When cleaning the enameled cast iron routinely after a cooking session or a recipe, remember a few important tips. First, avoid washing the enameled cast iron immediately after cooking in it.

    A 2008 review paper written by Philips researcher Clemens J. M. Lasance notes that: "Although there is an analogy between heat flow by conduction (Fourier's law) and the flow of an electric current (Ohm’s law), the corresponding physical properties of thermal conductivity and electrical conductivity conspire to make the behavior of heat flow ...

  9. Pinch analysis - Wikipedia

    Temperature vs. heat load diagram of hot stream (H 2 O entering at 20 bar, 473.15 K, and 4 kg/s) and cold stream (R-11 entering at 18 bar, 303.15 K, and 5 kg/s) in a counter-flow heat exchanger. "Pinch" is the point of closest approach between the hot and cold streams in the T vs. H diagram.
