Heat transfer and flow resistance in a notched crossed-rib channel

  • Received Date: 24 Oct 2006

  • The investigation of heat transfer, flow resistance and the pressure across the channel in turbulator cooling channel with a special crossed-rib channel which has slots was studied experimentally, then got amount of experimental results. All experiments were made in stillness states. The method of vapor concreting heat transfer was adopted for the heat transfer experiments. The experiment was conducted in the range of Reynolds number from 5 000 to 45 000. Compared with the channels which are no slots, the same dimensions ones with slots have more significant effects on the whole heat transfer enhancement. Besides, the experimental comparisons of characteristics were made to the different slots width channels. For the channels of different slots width, the heat transfer effects of 4 mm slot width channel are best, the following are 2 mm, 6 mm and 8 mm in turn.
