Centrifugal Fan Blade Design

The redesign effort was geared towards meeting the design volute exit pressure while reducing the power required to operate the fan.

Centrifugal fan blade design.

The axstream s centrifugal compressor fan profiler and blade design software module is used to create and edit 3d airfoils for full or partial channel length. 9 to 16 blades of airfoil curved away from the direction of rotation. Axial and propeller fans. Namic design of a centrifugal impeller with the pressure ratio up to 6 2 zange neh et al.

Centrifugal fans come in four basic fan types each with its own specific purpose. In an axial fan the air flows in parallel to the shaft. Such a fan is also called a blower fan biscuit blower citation needed or squirrel cage fan because it looks like a hamster wheel. Centrifugal fan blade types.

A centrifugal fan is a mechanical device for moving air or other gases in a direction at an angle to the incoming fluid. It has ideal zero slope in h q. Radial blades are ideal for dust laden air or gas because they are less prone to blockage dust erosion and failure and have self cleaning properties as observed by mohamed ali 20. A method is presented for redesigning a centrifugal impeller and its inlet duct.

Axial propeller fans are more suited for applications with lower volumes and pressures. Centrifugal fans often contain a ducted housing to direct outgoing air in a specific direction or across a heat sink. The highest speed of the centrifugal fans. Fan parts impeller design the centrifugal fans impeller have five basic blade shapes and a number of impeller configurations i e dwdi double width double inlet or swsi single width single inlet.

It is common to classify axial fans upon their wheel like. Centrifugal fans with forwarded blades are suited for application with higher air flow volumes and pressures. The double discharge volute casing is a structural constraint and is maintained for its shape. Centrifugal compressor fan profiler and blade design software.

A very common type of centrifugal fan typically referred to as a centrifugal blower uses a squirrel cage type wheel with many forward curved blades. The impeller design will depend on the aerodynamic duty and the operating conditions. Suitable for higher static pressure up to 14 3 5 kpa. Deep blades for efficient expansion with the blade passages.

Given the high performance of the baseline impeller the redesign adopted a high. Centrifugal fan design methodologies studies on radial tipped centrifugal fan 111 under dust laden conditions. Radial these are high pressure fans with medium airflow. Radial bladed fans are best for industrial applications where there is dust or in environments where there is gas or moisture in the air.

A wide range of geometric tools and interactive charts allows users to configure the centrifugal radial or compressor.
