Özet:Energy efficiency has become one of the most important concerns of the world recently. Rate of decrease of energy resources have been accelerated due to increased population and unconscious consumption. As a result, energy efficient new generation products are on the agenda for environmental issues. Furthermore, the more efficient the product, the less costly it consumes energy. Hence, people are encouraged to use energy efficient products which enables them to save more money. In addition, it has become obligatory to manufacture energy efficient products rather than being an option. This is regulated by certain rules determined by relevant commissions around the world. White goods, so dishwashers, have to obey certain consumption levels according to these regulations as well. In this thesis, a centrifugal pump for circulating the washing liquid in an energy efficient dishwasher, especially Arçelik dishwasher, is designed and constructed. The pump is required to deliver 60 l/min at 3020 rpm against a 300 mbar system. After the construction, its performance is evaluated by means of both Computational Fluid Dynamics (CFD) and laboratory experiments. CFD helps the designer save time and money. Several geometries and conditions can be analyzed in certain time without requiring any real product but eligible hardware and software. After deciding the final design, prototypes are produced and tested under actual conditions. At the end of this study, performance target is reached with acceptable energy efficiency.
