Standalone RaNS may yield a reasonable estimate of the wall-shear stress and turbulent drag if a proper wall-function is prescribed, but detailed turbulence statistics cannot be obtained, especially at the wall. This lack in modeling is addressed here by a stochastic deconvolution strategy based on a stochastic one-dimensional turbulence (ODT) model. Here, a one-way coupling strategy is proposed in which a forcing term is computed from the balanced RaNS solution that is in turn utilized in the ODT model. The temporally developing ODT solution exhibits turbulent perturbations but relaxes toward the local RaNS solution due to resolved molecular-diffusive processes. It is demonstrated that the approach is able to recover the distribution of positive wall-shear stress fluctuations in turbulent channel flow. When formulated as post-processing tool, it is suggested that RaNS can be enhanced by ODT providing economical means for local high-fidelity numerical modeling based on a low-fidelity flow solution.}, language = {en} } @misc{HallSchmidtWaggeetal., author = {Hall, Braeden and Schmidt, Kathleen and Wagge, Jordan and Lewis, Savannah C. and Weissgerber, Sophia C. and Kiunke, Felix and Pfuhl, Gerit and Stieger, Stefan and Tran, Ulrich S. and Barzykowski, Krystian and Bogatyreva, Natalia and Kowal, Marta and Massar, KarlIJn and Pernerstofer, Felizitas and Sorokowski, Piotr and Voracek, Martin and Chartier, Christopher R. and Brandt, Mark J. and Grahe, Jon E. and {\"O}zdoğru, Asil A. and Andreychik, Michael R. and Chen, Sau-Chin and Evans, Thomas R. and Hautekiet, Caro and IJzerman, Hans and Kačm{\´a}r, Pavol and Krafnick, Anthony J. and Musser, Erica D. and Vergauwe, Evie and Werner, Kaitlyn M. and Aczel, Balazs and Arriaga, Patr{\´i}cia and Batres, Carlota and Beaudry, Jennifer L. and Cova, Florian and Ďurbisov{\´a}, Simona and Cramblet Alvarez, Leslie D. and Feldman, Gilad and Godbersen, Hendrik and Gottfried, Jaroslav and Haeffel, Gerald J. and Hartanto, Andree and Isloi, Chris and McFall, Joseph P. and Milyavskaya, Marina and Moreau, David and Nos{\´a}ľov{\´a}, Ester and Papaioannou, Kostas and Ruiz-Fernandez, Susana and Schr{\"o}tter, Jana and Storage, Daniel and Vezirian, Kevin and Volz, Leonhard and Weisberg, Yanna J. and Xiao, Qinyu and Awlia, Dana and Branit, Hannah W. and Dunn, Megan R. and Groyecka-Bernard, Agata and Haneda, Ricky and Kielinska, Julita and Kolle, Caroline and Lubomski, Paweł and Miller, Alexys M. and M{\ae}kel{\ae}, Martin J. and Pantazi, Mytro and Ribeiro, Rafael R. and Ross, Robert M. and Sorokowska, Agnieszka and Aberson, Christopher L. and Vassiliou, Xanthippi Alexi and Baker, Bradley J. and Bognar, Miklos and Cong, Chin Wen and Danvers, Alex F. and Davis, William E. and Dranseika, Vilius and Dumbravă, Andrei and Farmer, Harry and Field, Andy P. and Forscher, Patrick S. and Graton, Aur{\´e}lien and Hajdu, Nandor and Howlett, Peter A. and Kabut, Radosław and Larsen, Emmett M. and Lee, Sean T.
