Local well-posedness of Kolmogorov's two-equation model of turbulence in fractional Sobolev Spaces

Autor: Kosewski, Przemysław

We study Kolmogorov's two-equation model of turbulence on $d-$dimensional torus. First, the local existence of the solution with the initial data from non-homogeneous fractional Sobolev spaces (Bessel potential spaces) $H^s$ with $s>\frac{d}{2}$ is p

Existence and regularity result for Stokes system with special inlet/outlet condition

Autor: Wołos, Kamil, Kosewski, Przemysław

Our aim is to analyse special type of boundary conditions, created to simulate flows like in cardiovascular and respiratory systems. Firstly, we will describe model of viscous, incompressible fluid in a domain consisting many inlets and outlets with

Global in time solution to Kolmogorov's two-equation model of turbulence with small initial data

Autor: Kosewski, Przemysław, Kubica, Adam

We prove the existence of global in time solution to Kolmogorov's two-equation model of turbulence in three dimensional domain with periodic boundary conditions under smallness assumption imposed on initial data.

Local in time solution to Kolmogorov's two-equation model of turbulence

Autor: Kosewski, Przemysław, Kubica, Adam

We prove the existence of local in time solution to Kolmogorov's two-equation model of turbulence in three dimensional domain with periodic boundary conditions. We apply Galerkin method for appropriate truncated problem. Next, we obtain estimates for

Publikováno v: IEEE Software, vol.33, no. 3, pp. 35-41 (May-June 2016)

Modern software-based services are implemented as distributed systems with complex behavior and failure modes. Many large tech organizations are using experimentation to verify the reliability of such systems. We use the term "Chaos Engineering" to r

Effect of the Abutment Rigidity on the Wear Resistance of a Lithium Disilicate Glass Ceramic: An In Vitro Study

Autor: Przemysław Kosewski, Francesco De Angelis, Edoardo Sorrentino, Agnieszka Mielczarek, Matteo Buonvivere, Camillo D’Arcangelo

Publikováno v: Journal of Functional Biomaterials, Vol 14, Iss 8, p 395 (2023)

Lithium disilicate (LDS) glass ceramics are among the most common biomaterials in conservative dentistry and prosthodontics, and their wear behavior is of paramount clinical interest. An innovative in vitro model is presented, which employs CAD/CAM t
