In subject area: Physics and Astronomy Thermal phenomena refer to the effects of temperature on mechanical responses of microsystems, including thermal strains, coefficient of thermal expansion (CTE) variations, and changes in material parameters like Young’s modulus. AI generated definition based on:...
a measure of the ability of a substance to conduct heat, determined by the rate of heat flow normally through an area in the substance divided by the area and by minus the component of the temperature gradient in the direction of flow: measured in watts per metre per kelvin. Symbol:λork...
Moreover, the direct measurement of temperature as the energy of particles would of course be very difficult to carry out in practice. For these reasons, a conventional but convenient unit of temperature, the degree, is used in physics. It is defined as one-hundredth of the difference between...

Intuitively, the basic physics behind all our above mentioned numerical and analytical findings can also be understood by means of the following simple arguments: As long as heating is insignificant, we may focus on the dynamics within the initially populated energy interval Δ (see above (7))....

Although thermal waves are ubiquitous in nature and engineering, the development of diagnostic tools capable of elucidating the roles of reaction and transport remains an unmet need. This limits our comprehension of the physics and ability to predict wav
The model was not based on empirical formulas and assumed thermal resistance,and each symbol had definite physical meaning.The result showed that effective thermal conductivity had a negative correlation with the tortuosity fractal dimension,porosity,areal fractal dimension and hot air temperature,while ...
It is denoted by the symbol k or λ and the unit is W/m·K. Thermal conductivity of suspensions mainly depends on the particle volume concentrations, particle size and shape, thermal conductivity of particles and fluids, and fluid temperature (Chandrasekar, Suresh, & Senthilkumar, 2012; ...
The symbol \({{{\mathcal{A}}}\) means the thermodynamic limit of \({{{\mathcal{A}}}_{L}\), while the order of the limit is always in the aforementioned one. We restrict the class of the Hamiltonians, observables, and initial states to simple ones. The Hamiltonian of the system...
