• Theoretical and experimental flow analysis through the model water turbine stage

  Publikacja

  • M. Banaszek

  - Rok 2005

  W artykule zaprezentowano teoretyczną i eksperymentalną analizę przepływu przez stopień modelowej turbiny wodnej. Przedstawiono rozwiązanie zadania prostego dla dwuwymiarowego modelu przepływu. Zaprezentowano przykład numerycznej symulacji przepływu za pomocą komeryjnych kodów obliczeniowych oraz porównano wyniki symulacji numerycznych przepływu z wynikami badań eksperymentalnych.

• Investigations On Water Circulation in Animal Sea-Water Basins – On the Example of Seals′ Breeding Pools

  Publikacja

  • P. Zima

  - Polish Maritime Research - Rok 2017

  This paper presents general comments concerning investigations on water circulation in animal breeding pools containing sea water. As an example are given results of computer simulation of water circulation in seals’ breeding pools situated in Marine Station at Hel, belonging to Oceanographic Institute, Gdansk University. A mathematical model of three main pools was prepared with taking into account their inflow and outflow water...

• Numerical Simulations and Tracer Studies as a Tool to Support Water Circulation Modeling in Breeding Reservoirs

  Publikacja

  • P. Zima

  - Archives of Hydro-Engineering and Environmental Mechanics - Rok 2014

  The article presents a proposal of a method for computer-aided design and analysis of breeding reservoirs in zoos and aquariums. The method applied involves the use of computer simulations of water circulation in breeding pools. A mathematical model of a pool was developed, and a tracer study was carried out. A simplified model of two-dimensional flow in the form of a biharmonic equation for the stream function (converted into...

  To secure the proper conditions of life for sea mammals existing in closed systems one has to maintain the character of the breeding basins (i.e. shape, dimensions, facing of walls and bottom, quality and motion of water) as natural as possible. An appropriate system of water exchange plays a very important role here. A full renewal of water is time-consuming, expensive and troublesome, so can be made only periodically, and should...

• Two-phase water-air flow measurement using gamma-ray absorption technique – plug flow

  Dane Badawcze

  open access

  • M. Zych
  • R. Hanus
  • D. Świsulski

  The attached datasets contains the measurement results of the air-water flow in a horizontal pipeline. Flow type: plug flow. The data shows the pulse counts of the two radiometric sets. Each of these kits consisted of a QSA Global Am-241 gamma ray source and a Tesla SKG-1 type NaI(Tl) scintillation probe. The pulses were recorded using a dedicated EC...

• Modelowanie wymiany wody w zbiornikach hodowlanych przy użyciu zmodyfikowanego modelu tłokowego na przykładzie basenów hodowlanych dla fok

  Publikacja

  • P. Wielgat

  - Rok 2015

  Niniejszy artykuł opisuje sposób prostego modelowania wymiany wody w basenach hodowlanych fokarium Stacji Morskiej Instytutu Oceanografii Uniwersytetu Gdańskiego. W celu rozpoznania warunków wymiany wody oraz udziału stref zastoiskowych w basenach posłużono się dwiema uzupełniającymi się metodami. Były to badania traserowe z wykorzystaniem znacznika fluororescencyjnego oraz komputerowe obliczenia rozkładu linii prądu z użyciem...

• Detection of People Swimming in Water Reservoirs with the Use of Multimodal Imaging and Machine Learning

  Publikacja

  • J. Konert
  • A. Dradrach
  • J. Rumiński

  - Rok 2024

  Every year in many countries, there are fatal unintentional drownings in different water reservoirs like swimming pools, lakes, seas, or oceans. The existing threats of this type require creating a method that could automatically supervise such places to increase the safety of bathers. This work aimed to create methods and prototype solutions for detecting people bathing in water reservoirs using a multimodal imaging system and...
