Abstract In refrigeration systems, evaporative condensers have two main advantages compared to other condensation heat exchangers: They operate at lower temperature than traditional air-cooled and require a quantity of water pumping power towers. The mass transfer that occur on tube batteries are difficult study. aim this work is apply an experimental approach investigate the performance conden...

Excessive noise generated by roller coasters during operation is a significant issue for amusement parks located near residential and business districts. Previous work showed that filling the rails with sand and pea gravel can provide noise reduction levels of up to 10 and 15 decibels. However, using damping materials may require additional support structures to accommodate the weight increase ...
