Deflection Temperature Testing of Plastics Deflection Temperature Testing of Plastics. The deflection temperature is a measure of a polymer's ability to bear a given load at elevated temperatures. The deflection temperature is also known as the 'deflection temperature under load' (DTUL), 'heat deflection temperature', or 'heat distortion temperature' (HDT).

Deflagration A log in a fireplace. Deflagration (Lat: de + flagrare, to burn down) is subsonic combustion propagating through heat transfer; hot burning material heats the next layer of cold material and ignites it. Most fires found in daily life, from flames to explosions, are deflagrations.

Methods of Heat Transfer Heat Transfer by Radiation. A final method of heat transfer involves radiation. Radiation is the transfer of heat by means of electromagnetic waves. To radiate means to send out or spread from a central location. Whether it is light, sound, waves, rays, flower petals, wheel spokes or pain, if something radiates then it protrudes or spreads outward from an origin.

Multiphysics Cyclopedia Note that the term convection in heat transfer usually refers to the combination of heat transfer by conduction and advection, where advection refers to heat transfer due to bulk fluid motion. In the field of transport phenomena, and also in this text, convection is synonymous with advection.

Latent heat Latent heat, energy absorbed or released by a substance during a change in its physical state (phase) that occurs without changing its temperature. The latent heat associated with melting a solid or freezing a liquid is called the heat of fusion; that associated with vaporizing a liquid or a solid or condensing a vapour is called the heat of vaporization.

- HEAT CONDUCTION. When a temperature gradient exist in a material, heat flows from the high temperature region to the low. temperature region. The heat transfer mechanism is referred to as conduction and the heat transfer rate has been. found to be proportional to the temperature gradient normal to the heat transfer surface. For a 1-dimensional.

Latent Heat Latent Heat of Fusion is the latent heat (explained above) when phase of the substance changes from Solid to Liquid phase. Latent heat of Fusion is denoted by LF. Also fuse means melting. For a particular substance Latent heat of Vaporization is generally greater than its Latent heat of Fusion.

What is heat strain? heat strain or the thermal strain is caused due to the temperature changes. A solid body expands as the temperature increases and contracts as the temperature decreases.this causes the thermal strain. for a homogeneous and isotropic body the thermal strain is caused by change in temperature.

Deflection (engineering) Deflection (engineering) In engineering, deflection is the degree to which a structural element is displaced under a load. It may refer to an angle or a distance. The deflection distance of a member under a load is directly related to the slope of the deflected shape of the member under that load and can be calculated by integrating the function that mathematically describes the slope of the member under that load.
