  Purpose The purpose of this paper is the application of the computational fluid dynamics model simulating the blood flow within the aorta of an eight-year-old patient with Coarctation of Aorta. Design/methodology/approach The numerical model, based on commercial code ANSYS Fluent, was built using the multifluid Euler–Euler approach with the interaction between the phases described by the kinetic theory of granular flow (KTGF). Findings A...

  The article presents the results of a computational fluid dynamics (CFD) analysis of gas-liquid multiphase flow. The simulation was conducted using CFD code and the Euler–Euler approach. The presented study relates to the non–reactive, steady-state, turbulent flow of water and carbon dioxide mixture in a 3D pipe. Separation phenomenon between phases is observed. The solution was obtained using a mixture model. Different values...

  - JOURNAL OF INDUSTRIAL AND ENGINEERING CHEMISTRY - Year 2019

  Residence time distribution (RTD) provides information about average hydraulic residence time and the distribution of material in the reactor. A method for determining RTD for reactors with very short hydraulic residence times is deconvolution based on extraction of real RTD by the analysis of a non-ideal input signal. The mean residence time and dispersion were determined for the spinning fluids reactor (SFR). For the first time...

  Przedmiotem badań były poliuretany o zawartości 30% segmentów sztywnych,charakteryzujące się obecnością globul i sferolitów. Badania za pomocą mikro Ramana wykazały różny skład chemiczny w wymienionych mikroobszarach. W globulach stwierdzono zanik obecności segmentów giętkich lub ich bardzo znikomą ilość w porównaniu z matrycą i sferolitami.

  - IEEE TRANSACTIONS ON INDUSTRIAL ELECTRONICS - Year 2020

  The paper presents the control possibility of five phase induction machines. In the proposed solution the machine model vector form is not transformed to the (dq)-coordinate system, that is connected to rotor flux vector, but utilizes the stationary system ( αβ ). Moreover, the nonlinear model linearization is based on demonstrated nonlinear variables transformation for i-orthogonal ( αβ )(n) planes. By introducing the backstepping...
