Conjugate heat transfer in turbulent pipe flow with azimuthally non-uniform heating
Jonathan Neuhauser, Davide Gatti, Bettina Frohnapfel
Turbulent conjugate heat transfer (CHT) in pipes with azimuthally non-uniform heating is studied theoretically and numerically with a focus on low- fluids. While the i…

Critical assessment of RANS Models for Turbulent Heat Transfer in Low-Prandtl-Number Forced Convection
Luca Marocco, Jonathan Schmitt, Jonathan Neuhauser +2
RANS modeling of turbulent heat transfer in liquid metals remains challenging because the very low Prandtl number weakens the similarity between momentum and thermal transport. Sev…

Accelerating Extremum Seeking Convergence by Richardson Extrapolation Methods
Jan-Henrik Metsch, Jonathan Neuhauser, Jerome Jouffroy +2
In this paper, we propose the concept of accelerated convergence that has originally been developed to speed up the convergence of numerical methods for extremum seeking (ES) loops…
