Radiometric force on a sphere in a rarefied gas flow based on the Cercignani-Lampis model of gas-surface interaction
Denize Kalempa, Felix Sharipov
The radiometric force on a sphere due to its thermal polarization in a rarefied gas flow being in equilibrium is investigated on the basis of a kinetic model to the linearized Bolt…

Alexander Marsteller, Beate Bornschein, Lutz Bornschein +19
The KArlsruhe TRItium Neutrino experiment (KATRIN) aims to measure the effective electron anti-neutrino mass with an unprecedented sensitivity of , u…
Transport coefficients of multi-component mixtures of noble gases based on ab initio potentials. Viscosity and thermal conductivity
Felix Sharipov, Victor J. Benites
The viscosity and thermal conductivity of binary, ternary and quaternary mixtures of helium, neon, argon, and krypton at low density are computed for wide ranges of temperature and…
Drag and thermophoresis on a sphere in a rarefied gas based on the Cercignani-Lampis model of gas-surface interaction
Denize Kalempa, Felix Sharipov
The influence of the gas-surface interaction law on the classical problems of viscous drag and thermophoresis on a spherical particle with high thermal conductivity immersed in a m…
Comparison of the Shakhov and ellipsoidal models for the Boltzmann equation and DSMC for ab initio-based particle interactions

In this paper, we consider the capabilities of the Boltzmann equation with the Shakhov and ellipsoidal models for the collision term to capture the characteristics of rarefied gas…
Lattice Boltzmann approach to rarefied gas flows using half-range Gauss-Hermite quadratures: Comparison to DSMC results based on ab initio potentials
Victor E. Ambrus, Felix Sharipov, Victor Sofonea
In this paper, we employ the lattice Boltzmann method to solve the Boltzmann equation with the Shakhov model for the collision integral in the context of the 3D planar Couette flow…
Modelling of gas dynamical properties of the KATRIN tritium source and implications for the neutrino mass measurement
L. Kuckert, F. Heizmann, G. Drexlin +5
The KATRIN experiment aims to measure the effective mass of the electron antineutrino from the analysis of electron spectra stemming from the beta-decay of molecular tritium with a…
Modelling of transport phenomena in gases based on quantum scattering
Felix Sharipov
A quantum interatomic scattering is implemented in the direct simulation Monte Carlo (DSMC) method applied to transport phenomena in rarefied gases. In contrast to the traditional…
