A Radiation Algorithm with Correlated-k Distribution. Part I: Local Thermal Equilibrium
A new radiation scheme is proposed that uses the correlated-k distribution (CKD) method. The definition of the k-distribution function, the transformation between frequency space and k space, and the upper limit of the absorption coefficient in cumulative probability space (CPS) are discussed. The corresponding relation between each interval in CPS and the heating rate profile provides a method...
متن کاملMultigroup Correlated-k Distribution Method for Nonequilibrium Atomic Radiation
Accurate and efficient modeling of shock-layer radiative heat loads is critical for many spacecraft designs. A correlated-k distribution method has been developed for the most important atomic species (N and O), which provides great accuracy with high numerical efficiency for the evaluation of radiative transfer in a hot plasma. Challenges posed by typical nonequilibrium gas conditions and extr...
متن کاملThermal Equilibrium Distribution of Wavefunctions
It is well known that in quantum theory, thermal equilibrium at inverse temperature β corresponds to the density matrix (1/Z) exp(−βH). But a density matrix that is not pure can arise from many different distributions of the wavefunction. We address in this paper the question which distribution of the wavefunction corresponds to thermal equilibrium, or, in other words, which distribution of the...
متن کاملModelling Bidispersive Local Thermal Non-Equilibrium Flow
In this work, we present a system of equations which describes non-isothermal flow in a bidispersive porous medium under conditions of local thermal non-equilibrium. The porous medium consists of macro pores, and in the solid skeleton are cracks or fissures which give rise to micro pores. The temperatures in the solid skeleton and in the fluids in the macro and micro pores are all allowed to be...
متن کاملExperimental Investigation of the Alumina/Paraffin Thermal Conductivity Nanofluids with a New Correlated Equation on Effective Thermal Conductivity
Liquid paraffin as a coolant fluid can be applied in electronic devices as a result to its suitable capabilities such as electrical insulating, high heat capacity, chemical and thermal stability, and high boiling point. However, the poor thermal conductivity of paraffin has been confined its thermal cooling application. Addition of high conductor nanoparticles to paraffin can fix this drawback...
