A method for analysing ram pressure characteristics of impeller pump rotor
PublikacjaW pracy przedstawiono metodę wyznaczania kąta wypływu strumienia z wirnika w oparciu o określoną eksperymentalnie charakterystykę ciśnienia w funkcji natężenia przepływu. Metoda może być wykorzystana do określenia kąta napływu na palisadę łopatkową za kołem wirnikowym w sytuacji braku mozliwości jego pomiaru.

Description of the hydrodynamic pressure field function around the ship hull
PublikacjaW artykule przedstawiono metodę aproksymacji pola hydrodynamicznego okrętu, wykorzystując pole obliczone metodą elementów skończonych. Punkty kontrolne umieszczono w środku paneli rozmieszczonych na kadłubie statku, na powierzchni dna morskiego oraz na powierzchni swobodnej; w p-ktach tych znajdują się osobliwości w postaci źródeł, upustów i/lub dipoli. Przedstawione wyniki obliczeń zostały uzyskane przy użyciu tych pierwszych...

The innovative experimental rig for wood steam drying at atmospheric pressure
PublikacjaThe high cost of fossil fuel and soaring consumer interest have encouraged people in the wood industry to look for faster and more energy-efficient methods to dry lumber. The air-steam mixture as medium of drying process was used in a laboratory kiln especially arranged for that reason. Experimental rig is based on automatic control system. At the time of drying measurements of the internal temperature, wood temperature, moisture...
