Centrifugal fan design calculations pdf.

Differences such as efficiency or flow rate occur in the type of fan due to particular design advantages that favour one characteristic over another. There are a number of fan types. In this chapter we shall define fan pressures and examine some of the basic theory of fan design the results of combining fans in series and parallel configurations the theory of fan testing and booster fan installations. Fan pressures a matter that has often led to confusion is the way in which fan pressures are defined.

Types the major types of centrifugal fan are. A sample fan based on the optimum. Backward inclined airfoil forward curved and radial tip. Radial fans are industrial workhorses because of their high static pressures upto 1400 mm wc and ability to handle heavily contaminated airstreams.

Radial blade or radial tip. All of which have individual benefits volume pressure speed power efficiency etc but all of them will shift gases at the same rate based upon the input power. Radial forward curved and backward curved see figure 5 3. A modern optimum design method for a centrifugal fan has been presented using a computational fluid dynamics cfd technique to replace the conventional method.
