A simple operator split of this second order wave equation into two coupled first order equations is performed, allowing these split equations to be solved symplectically. Orders of symplectic time integration ranging from first to fourth along with orders of spatial derivatives ranging from second to sixth are explored. The case of cylindrical acoustic spreading in air under a constant velocity in a 2D square structured domain is considered. The variation of the computed time-of-flight, frequency, and wave length are studied with varying grid resolution and the deviations from the analytical solutions are determined. It was found that symplectic time integration interferes with finite difference spatial derivatives higher than second order causing unexpected results. This is actually beneficial for unstructured finite volume tools like OpenFOAM where second order spatial operators are the state-of-the art. Cylindrical acoustic spreading is simulated on an unstructured 2D triangle mesh showing that symplectic time integration is not limited to the spatial discretization paradigm and overcomes the numerical diffusion arising with the in-built numerical methods which hinder wave propagation.}}, author = {{Inguva, Venkatesh and Feldmann, Nadine and Claes, Leander and Koturbash, Taras and Hahn-Jose, Thomas and Koutcherov, Vladimir and Kenig, Eugeny}}, journal = {{Engineering Reports}}, title = {{{An explicit symplectic approach to solving the wave equation in moving media}}}, doi = {{10.1002/eng2.12573}}, year = {{2022}}, } @inproceedings{31070, author = {{Bothe, Mike and Lutters, Nicole and Kenig, Eugeny Y.}}, location = {{Frankfurt am Main}}, title = {{{Untersuchung von Gefahrensituationen bei industriellen Absorption/Desorption-Prozessen mittels dynamischer Simulation}}}, year = {{2022}}, } @inproceedings{33522, author = {{Bernemann, Sören Antonius and Maćkowiak, Jan and Maćkowiak, Jerzy and Bertling, René and Lutters, Nicole and Kenig, Eugeny}}, keywords = {{CFD, simulation, agricultural waste, multiphase}}, location = {{Frankfurt am Main}}, title = {{{Development of an innovative separation unit for nitrogen recovery from agricultural waste}}}, year = {{2022}}, } @inproceedings{33972, author = {{Mügge, Nils and Kronberg, Alexander and Glushenkov, Maxim and Inguva, Venkatesh and Kenig, Eugeny Y.}}, booktitle = {{1st Conference on Energy, Environment and Digital Transition E2DT}}, location = {{Mailand, Italien}}, title = {{{A Thermal Model for Recuperative Heat Engines Operating with Dense Working Fluids}}}, year = {{2022}}, } @inproceedings{33204, author = {{Al-Lami, Abbas Jarullah Sangoor and Kenig, Eugeny Y.}}, location = {{Würzburg}}, title = {{{Heat transfer enhancement with internally channeled tubes}}}, year = {{2022}}, } @inproceedings{33035, author = {{Mapura, Luz Alejandra and Kenig, Eugeny Y.}}, booktitle = {{Annual Meeting on Reaction Engineering and ProcessNet Subject Division "Heat and Mass Transfer"}}, location = {{Würzburg}}, title = {{{Effect of diffusivity and chemical reactions on the determination of mass transfer coefficients in columns with structured packing}}}, year = {{2022}}, } @inproceedings{33254, author = {{Buckmann, Felix and Kenig, Eugeny}}, booktitle = {{Annual Meeting on Reaction Engineering and ProcessNet Subject Division "Heat and Mass Transfer"}}, location = {{Würzburg}}, title = {{{Experimental study on the condensation of pure substances in outer pillow-plate channels}}}, year = {{2022}}, } @inproceedings{40647, author = {{Mamedov, Tural and Schleicher, Eckhard and Schubert, Markus and Ehlert, Thomas and Kenig, Eugeny Y.}}, location = {{Frankfurt am Main}}, title = {{{Liquid flow morphology investigation in structured packings for offshore applications using a novel flow imaging sensor}}}, year = {{2022}}, } @inproceedings{31183, author = {{Dechert, Christopher and Kenig, Eugeny}}, location = {{Frankfurt am Main}}, title = {{{Untersuchung von kleinskaligen Flüssigkeitselementen auf mikrostrukturierten Packungsoberflächen}}}, year = {{2022}}, } @article{34228, author = {{Mügge, Nils and Kronberg, Alexander and Glushenkov, Maxim and Inguva, Venkatesh and Kenig, Eugeny Y.}}, isbn = {{978-88-95608-95-2}}, issn = {{2283-9216}}, journal = {{Chemical Engineering Transactions}}, location = {{Mailand, Italien}}, pages = {{175--180}}, title = {{{A Thermal Model for Recuperative Heat Engines Operating with Dense Working Fluids}}}, doi = {{10.3303/CET2296030}}, volume = {{96}}, year = {{2022}}, } @inproceedings{33485, author = {{Dechert, Christopher and Kenig, Eugeny}}, booktitle = {{Proceedings of the 12th international conference Distillation & Absorption 2022}}, location = {{Toulouse, France}}, title = {{{CFD-Based Investigation of the Packing Microstructure Influence on Droplet Behavior and Film Flow}}}, year = {{2022}}, } @inproceedings{31223, author = {{Mügge, Nils and Kronberg, Alexander and Glushenkov, Maxim and Kenig, Eugeny}}, booktitle = {{Heat Powered Cycles Conference 2022}}, location = {{Bilbao, Spain}}, title = {{{On Heat Regeneration Limitations in Heat Engines With Dense Working Fluids}}}, year = {{2022}}, } @inproceedings{31186, author = {{Ehlert, Thomas and Mamedov, Tural and Schubert, Markus and Kenig, Eugeny Y.}}, location = {{Frankfurt am Main}}, title = {{{Modellierung des Stofftransportes in einer geneigten Kolonne mit dem Ansatz der hydrodynamischen Analogien}}}, year = {{2022}}, }
