  This investigation is devoted to an analysis of the working process in a dual-fuel low-emission combustion chamber for a floating vessel’s gas turbine. The low-emission gas turbine combustion chamber with partial pre-mixing of fuel and air inside the outer and inner radial-axial swirlers was chosen as the object of research. When modelling processes in a dual-flow low-emission gas turbine combustion chamber, a generalized method...

  • P. Ziemiański

  - Problemy Zarządzania - Rok 2018

  As entrepreneurial teams become prevalent, it is important to study factors related to their creation and effectiveness. The goal of the current research was to analyze preferences towards working in a multicultural team (MCT) versus a single culture team (SCT) at different stages of the entrepreneurial process. The study involved students originating from various cultures with previous experience in both SCTs and MCTs as participants....

• Preliminary investigations of effect of conditions of FCAW process on diffusible hydrogen content in deposited metal

  Publikacja

  - Rok 2013

  One of the types of hydrogen degradation of steel welded joints is cold cracking. The direct cause of the formation of cold cracks is simultaneous presence of hydrogen, residual stresses and brittle structure. The way of preventing the occurring of degradation is to eliminate at least one of these factors. Practice has shown that the best solution is to control the amount of hydrogen in deposited metal. In this paper the state...

• Laboratory bioreactor with pH control system for investigations of hydrogen production in the dark fermentation process

  - Aparatura Badawcza i Dydaktyczna - Rok 2019

  The work presents the construction of a low-cost research bioreactor equipped with a pH control sys-tem. The developed bioreactor was applied for hydrogen production in the dark fermentation process using Enterobacter aerogenes ATCC 13048. Presented paper compares the results obtained during the process without and with pH regulation for different feed materials: glucose, energetic poplar hydro-lysates, acid whey and glycerol....

• Experimental investigations of fracture process in concrete by means of x-ray micro-computed tomography

  Publikacja

  • Ł. Skarżyński
  • J. Tejchman

  - STRAIN - Rok 2016

  W artykule pokazano doświadczalne wyniki badań procesu pękania w betonie stosując mikro-tomografię. Doświadczenia wykonano dla zginanych belek betonowych. Wyniki doświadczalne modelowano stosując MES na bazie modelu z degradacją sztywności sprężystej z nielokalnym osłabieniem. Beton symulowano jako materiał 4-fazowy. Uzyskano dobra zgodność wyników MES z doświadczeniami.

• Experimental Investigations of Fracture Process Using DIC in Plain and Reinforced Concrete Beams under Bending

  Publikacja

  • Ł. Skarżyński
  • J. Tejchman

  - STRAIN - Rok 2013

  The fracture behaviour of concrete and reinforced concrete beams under quasi-static three-point bending was comprehensively investigated with experiments at laboratory scale. The eight various concrete mixes were tested. The influence of the shape, volume and size of aggregate particles and reinforcement on concrete fracture under bending was studied. Displacements on the surface of concrete beams were measured by means of the...
