1. EXPERIMENTAL DETERMINATION OF HEAT TRANSFER CHARACTERISTIC IN AN ICE SLURRY GENERATOR / DETERMINAÇÃO EXPERIMENTAL DAS CARATERÍSTICAS DE TRANSFERÊNCIA DE CALOR DE UM GERADOR DE PASTA DE GELO
Um gerador de pasta de gelo foi desenvolvido para o estudo experimental de suas características de transferência de calor. Uma das características da pasta de gelo é que pode ser bombeada como qualquer líquido. O gerador de pasta de gelo é um evaporador, do tipo trocador de calor de superfície raspada com intensificação mecânica de transferência d

2. DETERMINAÇÃO EXPERIMENTAL DOS COEFICIENTES DE TRANSPORTE DA PASTA DE GELO EM TROCADORES DE CALOR DE PLACAS / EXPERIMENTAL DETERMINATION OF TRANSPORTATIONS COEFFICIENTS FOR ICE SLURRY IN PLATE HEAT EXCHANGERS
Ice slurry is an aqueous solution from which ice crystals are formed. These crystals possess high energy density, in the form of latent heat. Furthermore, the fact of being a slurry makes it an excellent energy carrier, for it can be easily pumped. The present work presents an experimental procedure to assess the heat transfer and the pressure loss, with pha

3. DETERMINAÇÃO EXPERIMENTAL DO COEFICIENTE DE TROCA DE CALOR EM UM GERADOR DE PASTA DE GELO / EXPERIMENTAL DETERMINATION OF THE HEAT TRANSFER COEFFICIENT IN AN ICE SLURRY GENERATOR
New ice crystal slurry thermal energy storage (TES) system has been developed for both HVAC and process cooling applications. The system uses an orbital rod evaporator (ORE), a vertical shell-and-tube heat exchanger with mechanical heat transfer augmentation, as a dynamic ice maker to generate liquid ice. Ice forms continuously without accumulation in the OR

4. TRANSPORT COEFFICIENTS OF ICE SLURRY IN PLATE HEAT EXCHANGER / COEFICIENTES DE TRANSPORTE DA PASTA DE GELO EM UM TROCADOR DE CALOR DE PLACAS
O uso da pasta de gelo começou recentemente a ser aplicado em sistemas de refrigeração e condicionamento de ar. Como principais vantagens deste fluido, podem ser citados: a possibilidade de armazenar calor latente do gelo e a possibilidade de ser bombeado como a água fria. Assim, o pasta de gelo pode ser usado para o armazenamento térmico no lugar da á

5. Ballistic Disruption of Penicillium chrysogenum Cells
The use of glass beads in a high-speed mixing device to rupture organisms was applied to molds. The use of a mixer in which the propellor shaft enters from the top into a metal mixing chamber made it possible to immerse the whole device in a salt water and ice mixture so that the temperature of the glass-bead slurry could be kept below 5 C without difficulty

6. Hemagglutination by BK Virus, a Tentative New Member of the Papovavirus Group
Some characteristics of hemagglutination (HA) by the BK virus, a new candidate for the papovavirus group, have been studied. Hemagglutinin prepared from cell cultures was found to be partially masked by inhibitors which could be dissociated from the virus by incubation at 37 C or by fluorocarbon extraction. Optimal conditions for HA are outlined. In routine
