• Structural properties of water: Comparison of the SPC, SPCE, TIP4P and TIP5P models of water

  Publication

  • J. Zielkiewicz

  - Year 2005

  Dla czterech najpopularniejszych modeli wody obliczono wartości entropii absolutnej ciekłej wody w temperaturze 298 K, średnią liczbę wiązań wodorowych tworzonych przez cząsteczkę wody, średni czas życia wiązania wodorowego, średni czas życia cząsteczki wody w stanie związanym (gdy tworzy ona co najmniej jedno wiązanie wodorowe) oraz średnią energię wiązania wodorowego. Otrzymane rezultaty porównano z eksperymentem. Uzyskane wyniki...

• Comparison of properties of the new electro-mechanical model and circumferential model of the inductive-dynamic drive

  Publication

  • P. Jankowski
  • M. Wołoszyn

  - INTERNATIONAL JOURNAL OF APPLIED ELECTROMAGNETICS AND MECHANICS - Year 2019

  The article presents a new electromechanical model of inductive-dynamic drive. The model is implemented in two environments: Maxwell for analyzing electrodynamic phenomena including moving of the disc and Ansys which allows for stress analysis on the basis of the volume forces imported from Maxwell. Additionally, a model validation by comparing with the existing circumferential model was carried out.

  - WATER RESOURCES RESEARCH - Year 2005

  This paper presents experimental verification of the mathematical model of unsaturated flow in double‐porosity soils developed by the asymptotic homogenization method. A series of one‐dimensional infiltration experiments was carried out in a column filled with a double‐porosity medium composed of a mixture of sand and sintered clayey spheres arranged in a periodic manner. The unsaturated hydraulic properties of each porous material...

• A COMPARISON OF WEAR PROPERTIES OF WATER LUBRICATED NBR AND PTFE SLIDING BEARINGS

  Publication

  • E. Wojtowicz

  - TRIBOLOGIA - Year 2019

  The excessive wear of a journal shaft can be caused by many factors, for example, working conditions (e.g., temperaturę, slip speed, the type of lubricant), pressure, the type of material used on the bearings and shafts and their roughness, as well as contamination remaining in the system. This paper presents the roughness profiles co-operating with a rubber (NBR) and polytetrafluoroethylene (PTFE) bushes. The conditions of cooperation...

• Comparison of single microjet cooling with water, ethanol and HFE7100 as test fluids

  Publication

  • T. Muszyński

  - Year 2013

  The paper presents the investigation of a single microjet cooling forming an thin liquid film on the impingement surface of specially designed rig. The basis of microjet technology is to produce laminar jets, which when impinging the surface have a very high kinetic energy at the stagnation point. Applied technology of jet production can result with the size of jets ranging from 20 to 500μm in breadth and 20 to 100μm in width....

• A Comparison of Simplified Two-dimensional Flow Models Exemplified by Water Flow in a Cavern

  Publication

  • P. Zima

  - Archives of Hydro-Engineering and Environmental Mechanics - Year 2017

  The paper shows the results of a comparison of simplified models describing a two-dimensional water flow in the example of a water flow through a straight channel sector with a cavern. The following models were tested: the two-dimensional potential flow model, the Stokes model and the Navier-Stokes model. In order to solve the first two, the boundary element method was employed, whereas to solve the Navier-Stokes equations, the...

  - NUCLEAR ENGINEERING AND DESIGN - Year 2017

  The paper focuses on the presentation and comparison of basic nodal and expanded multi-nodal models of the Pressurized Water Reactor (PWR) core, which includes neutron kinetics, heat transfer between fuel and coolant, and internal and external reactivity feedback processes. In the expanded multi-nodal model, the authors introduce a novel approach to the implementation of thermal power distribution phenomena into the multi-node...
