| Title: | Simulation of unsteady flow with cavitation in plastic pipes using the discrete bubble cavity and Adamkowski models | Authors: | Urbanowicz, K Bergant, A Duan, HF |
Issue Date: | 2019 | Source: | IOP conference series : materials science and engineering, 2019, v. 710, no. 1, 12013 | Abstract: | The work presents two modified cavitation models for the simulation of transient flow in pressure plastic pipes. The first model is a discrete bubble cavitation model, the prototype of which was presented by Shu, and the second one is the Adamkowski model. In the latter model, the problem encountered in the classical model (DVCM-discrete vapour cavitation model) related to artificial damping of pulsation, which results from approximate timing of cavity opening and collapse. In both models, the corrected efficient calculation of Zielke convolution integral was used to simulate the unsteady wall shear stresses. The numerical results from the two models agree well with the results of measurement in the literature. | Publisher: | Institute of Physics Publishing | Journal: | IOP conference series : materials science and engineering | ISSN: | 1757-8981 | EISSN: | 1757-899X | DOI: | 10.1088/1757-899X/710/1/012013 | Description: | 4th International Conference of Computational Methods in Engineering Science, CMES 2019, Poland, 21-23 November 2019 | Rights: | Published under licence by IOP Publishing Ltd.
