What is the difference between a centrifugal compressor and an axial-flow compressor?
The main difference is in how they operate, vs how they are maintained. Flow through a centrifugal compressor is turned perpendicular to the axis of rotation, while air in an axial compressor flows parallel to the axis of rotation.

Is centrifugal or axial compressor better?
Centrifugal compressors are preferred where simpler design and manufacturing is needed. Axial compressors operate more efficiently than the centrifugal compressors and are preferred in applications where higher gas flow and pressure ratio is needed.
What is the difference between the two basic types of compressors axial-flow and centrifugal flow?
Compressor types There are two basic types of compressors — axial flow and centrifugal flow. The difference between them is the way that the air flows through the compressor.
Why is axial-flow compressor preferred over centrifugal compressor?
Answer C is correct. Greater pressure ratios are possible, with axial compressors suitable for pressure ratios up to 10:1, while centrifugal compressors are suitable only for 4:1 pressure ratios. Axial compressors also require less frontal area and are more expensive to operate versus centrifugal compressors.
What are the advantages and disadvantages of axial flow compressor over centrifugal compressor?
Comparison between Axial Flow and Centrifugal Compressor
| AXIAL FLOW COMPRESSOR | CENTRIFUGAL COMPRESSOR |
|---|---|
| The pressure gradient for a single stage is very less. | It can create more differential pressure in a single stage. |
| It is very expensive and the machine is very heavy. | This machine is comparatively cost-effective. |
What is application of centrifugal compressor?
Applications of centrifugal compressor Gas turbines, in automobile turbochargers and supercharger. Oil refineries, natural-gas processing. Refrigeration, air-conditioning and HVAC. Manufacturing process compressed air for pneumatic tools.
What is axial centrifugal compressor?
Dynamic compressors include centrifugal and axial compressors. Both types operate by changing the velocity of gas and converting energy to pressure. Dynamic compressors accelerate airflow by drawing air in axially and spinning it outward (centrifugal compressors) or in a straight line (axial compressors).
What is an axial compressor used for?
Axial compressors are integral to the design of large gas turbines such as jet engines, high speed ship engines, and small scale power stations. They are also used in industrial applications such as large volume air separation plants, blast furnace air, fluid catalytic cracking air, and propane dehydrogenation.
What is the maximum pressure ratio of axial flow compressor?
Construction (Cont.) Axial flow compressor is also high speed machine & speed may even vary from 10000 to 30000 RPM. Generally, maximum pressure ratio achieved in a stage of axial compressor is about 1.12 to 1.2, hence to obtain pressure ratio of 12, attainable by axial flow compressor 15 to 20 stages are required. 7
What is the difference between axial and centrifugal compressors?
Centrifugal compressors are easier to design and manufacture compared to axial compressors. But centrifugal compressors can handle much less gas flow compared to the axial compressors. Centrifugal compressors can often create more differential pressure with a single compression stage.
How many stages are required for axial flow compressor?
Generally, maximum pressure ratio achieved in a stage of axial compressor is about 1.12 to 1.2, hence to obtain pressure ratio of 12, attainable by axial flow compressor 15 to 20 stages are required. 7 8. Working As the fluid enters and leaves in the axial direction, the centrifugal component in the energy equation does not come into play.
What are the advantages and disadvantages of axial flow compressor?
Advantages & Disadvantages of Axial Flow Compressor Advantages:- 1. High peak efficiency. 2. Small frontal area for given flow. 3. Straight through flow, allowing high ram efficiency. 4. Increased pressure rise due to increased number of stages with negligible losses. 21 22. Advantages & Disadvantages of Axial Flow Compressor Disadvantages:- 1.
