In this work, we develop for a complex fluid without structure evolution equations for the heat flux and the pressure stress tensor and its trace. With this set of equations, we obtain a telegrapher's type wave equation for each variable coupled to forced terms of the other variable. It ...
Conductivity Identification in the Heat Equation by the Heat Flux ☆Kadec's 1/4-theoremstability boundframeRiesz basisThe author considers the problem of determining the thermal conductivity of a semi-infinite rod, given the temperature and heat flow at the endpoint. That is, given f on [0,T...
We present an equation for the heat-flux vector that goes beyond Fourier's Law of heat conduction, in order to model shockwave propagation in gases. Our approach is motivated by the observation of a disequilibrium among the three components of temperature, namely, the difference between the tempe...
We show how using a special relativistic kinetic equation with a BGK- like collision operator the ensuing expression for the heat flux can be casted in the form required by Classical Irreversible Thermodynamics. Indeed, it is linearly related to the temperature and number density gradients and not...

By revisiting previous definitions, we show that one can define an energy current operator that satisfies the continuity equation for a general Hamiltonian in one dimension. This expression is useful for studying electronic, phononic and photonic energy flow in linear systems and in hybrid structures....
i would like to find out what equation has been used in Fluent for the calculation of Total Heat Transfer Flux. I checked my value with the equation Q = m.Cp.(dT) but got a small value whereas the value shown tehre is higher. ...
The present authors have developed a rapid method for estimation of the difference between geothermal fluxes of two adjacent places, from surface temperatures and some meteorological parameters, based on a heat budget equation for simple vegetation-free ground surfaces. As this method requires simultaneou...
