Kaller, Thomas (author), Doehring, Alexander (author), Hickel, S. (author), Schmidt, Steffen J. (author), Adams, Nikolaus A. (author)We present well-resolved RANS simulations of two generic asymmetrically heated cooling channel configurations, a high aspect ratio cooling duct operated with liquid water at (Formula Presented) and a cryogenic transcritical channel operated with methane at (Formula Presented). The former setup serves to investigate the interaction of...book chapter 2021

Kaller, Thomas (author), Pasquariello, Vito (author), Hickel, S. (author), Adams, Nikolaus A. (author)We present well-resolved large-eddy simulations of turbulent flow through a straight, high aspect ratio cooling duct operated with water at a bulk Reynolds number of Re<sub>b</sub> = 110 × 10<sup>3</sup> and an average Nusselt number of Nuxz = 371. The geometry and boundary conditions follow an experimental reference case and good agreement...journal article 2019

Kaller, Thomas (author), Hickel, S. (author), Adams, Nikolaus A. (author)We present the results of well-resolved large-eddy simulations (LES) of an asymmetrically heated high aspect ratio cooling duct (HARCD) with an aspect ratio of AR = 4.3 for two different wall temperatures. The temperature difference with respect to the bulk flow is ∆T = 40 K, respectively ∆T = 60 K. The HARCD is operated with liquid water at...conference paper 2018

(author)We present well-resolved large-eddy-simulations (LES) of a straight, high-aspect-ratio cooling duct (HARCD) at a bulk Reynolds number of Re = 110 • 10<sup>3</sup> and an average Nusselt number of Nu = 371. The geometry and boundary conditions have been defined together with Rochlitz et al. (2015), who conducted the experimental measurements...conference paper 2017
