Biography: Prof. Dr. Weizong received double Ph.D. degrees in electrical engineering from Xi'an Jiaotong University in Xi’an (China) and University of Liverpool (United Kingdom) in 2013. After that, he worked at Qian Xuesen Laboratory of Space Technology and studied advanced spacecraft propulsion. In 2015, he entered the PLASMANT research group at the University of Antwerp in Belgium supported by the European Marie Skłodowska-Curie (MSCA) Individual Fellowship and studied plasma based gases conversion into value added products. After some postdoctoral research years, he became a professor of space propulsion in 2018 at Beihang University. He is currently Dean of School of Astronautics at Beihang University. He is also the head of the Advanced Space Propulsion and Energy Laboratory (ASPEL). His current research activities include the fundamental physics, chemistry and applications of low temperature plasmas, by numerical modelling and experiments, for various applications, especially space propulsion and energy conversion applications. He is author of more than 100 peer-reviewed publications and gave more than 40 invited talks at academic conferences. He is serving as advisory board member of IOP Journal of Physics D: Applied Physics and editors of several journals including Space: Science & Technology、Chinese Space Science and Technology、Gas Physics and guest editor for 3 special issues in journals.

Biography: Sergey Timushev graduated from Moscow Aviation Institute in 1978. He received his Dr.Tech.Sc. degree in 1996 on numerical modeling of pressure pulsation in centrifugal pumps. He worked for Buran space program and within Moscow Aviation Institute for Arianne-Vulcain project, proposed the original acoustic-vortex method for numerical modeling of pressure pulsations and noise of bladed machines. He made many experimental and computational studies in the field of pressure pulsation and vibration in centrifugal turbopump units of Liquid Propellant Rocket Engines (LPRE), including reduction of pressure pulsation and vibration caused by cavitation, reverse flows, acoustical amplification. In 1986, he proposed the original method for numerical modeling of pressure pulsation in centrifugal machines. . In 2002-2004 he worked for EU scientific project NORMA on noise and vibration reduction in high-speed ships. Currently he works as a professor of department of Rocket engines of MAI and professor of turbomachinery. The last decade he works on the problem of computational prediction of pressure pulsation in centrifugal pumps and ventilators and reduction of vibration and noise in bladed machines. Recently he works on the creation of the new CFD-CAA code for prediction of noise emitted by tires and multicopter propellers. He is author and co-author of more than 100 scientific papers.

Speech Title: Acoustic-Vortex Decomposition Method for Modeling Pressure Pulsations and Noise in Blade Machines with Subsonic Flow

Abstract: The method for calculating the generation of pressure pulsations and noise emission by blade machines based on the decomposition of the compressible medium velocity field into vortex and acoustic modes. This method of acoustic-vortex decomposition of the basic equations of motion of a compressible medium leads to an inhomogeneous wave equation with respect to enthalpy pulsations, which include pseudo-sonic oscillations in the source vortex region and acoustic oscillations in the near-field and far-field. The source function in the wave equation is determined from the independent solution of the vortex mode equations. The boundary conditions for the wave equation are formulated using complex specific acoustic impedance and pseudo-sonic oscillations. This method allows for the consideration of the influence of inhomogeneity and turbulence of the flow, rotor interference, sound diffraction on the elements of the flow part, impedance characteristics of the machine surfaces, while ensuring the accuracy and speed of calculations. The acoustic-vortex method represents the noise source as a function of the vortex mode velocity field. This approach eliminates the arbitrariness and conventionality of the aeroacoustic analogy, defining the source, pressure pulsations and noise propagation in the near field as a direct result of numerical modelling.
