Best Answer

The centrifugal flow compressor has a single or two stage unit using an impeller. The axial flow compressor is a multi-stage unit using alternate rows of rotating (rotor) blades and stationary (stator) vanes.

An axial flow compressor compresses air by causing it to flow parallel to the axis of rotation, while a centrifugal compressor compresses air by directing it to rotate around an impeller. Axial compressors are more efficient for high flow rates and low pressure ratios, while centrifugal compressors are better suited for low flow rates and high pressure ratios.

What is the difference between centrifugal and axial compressor?

Centrifugal compressors use centrifugal force to increase the velocity of the air which is then converted to pressure, while axial compressors use rotating blades to accelerate and compress air in the axial direction. Centrifugal compressors are more compact and simpler in design, but axial compressors are more efficient and better suited for high flow rate applications.


How do you find centrifugal compressor is in surge?

A centrifugal compressor is in surge when the flow rate through the compressor is reduced below the minimum stable flow rate, leading to a reversal in the direction of flow. This condition can cause the compressor to vibrate, make noise, and potentially damage the equipment. Surge can be detected by monitoring key parameters such as suction pressure, discharge pressure, and flow rate.


How do you calculate surge in compressor?

To calculate surge in a compressor, you would need to determine the maximum flow rate and pressure that the compressor can handle without stalling. This can be done through performance mapping or testing. Surge is typically defined as the flow rate at which the compressor stalls due to flow reversal.


What is relation between mass flow rate and discharge pressure in reciprocating compressor?

The mass flow rate and discharge pressure in a reciprocating compressor are directly related. As the discharge pressure increases, it can result in a higher mass flow rate through the compressor. This relationship is important for determining the performance and efficiency of the compressor in various operating conditions.


How centripetal pump works?

Centripetal pumps, also known as centrifugal pumps, work by spinning an impeller that creates a centrifugal force, which moves the fluid towards the outer edges of the pump casing, generating pressure that forces the fluid out through an outlet. This constant rotation and centrifugal force create a continuous flow of fluid through the pump.

The frontal area of a centrifugal compressor as compared to axial flow compressor is larger or smaller?

the frontal area of a centrifugal compresor is more as compared to axial flow compressor for a given air flow. And for this reason axial compressors are being used in aircraft engines.

Why is the axial flow compressor better than the centrifugal compressor?

Higher peak volumetric efficiency. You don't have to turn the air at all, so you do not lose and energy in transforming it as you compress the air.


Why is the pressure ratio higher in a centrifugal compressor than an axial compressor?

There is a substantial increase in radius across the rotating blade rows of a centrifugal compressor, which is its primary distinguishing feature from the axial-flow compressors to get higher-pressure ratio. Who says the compression ratio on a centrifugal is higher than that of a screw compressor? Unless I`m not properly understanding the question, these facts are true: a screw (axial) compressor is a positive displacement machine, meaning everything that goes into it will come out. There are no losses for re-expansion etc. A centrifugal compressor`s impeller is designed with a given amount of `lift` which is basically the difference between suction and discharge pressures or compression ratio. Exceeding the designed lift capability results in a surge where the gas momentarily goes backwards through the impeller until the excess lift condition is corrected.


What is the disadvantages of centrifugal compressor?

A centrifugal pump cannot pump air, therefore cannot self prime, like a positive displacement pump.


What is the different between axial turbocharger and radial turbocharger?

An axial compressor uses many stages of "fans" with stators to compress air in the same direction as its original flow. An example of this is that of *most* turbojet engines' compressors. A radial (or centrifugal) compressor works at right angles to the airflow's original direction. An example of a radial compressor is the compressor on an automotive turbocharger.


Which is true when a radial compressor and an axial compressor with equal air flow and revolution are compared?

I don't understand the question. It would appear that you wish to compare a centrifugal compressor and an axial flow compressor operating at the same speed and delivering equal flow rates. What is the process fluid? What is the question? Is the "equal air flow" the mass flow rate? At what pressure differential would you like to consider these machines? What is it that you wish to compare? Is it weight, frontal area, mechanical efficiency, overall diameter, length, delivery temperature, input power or what?


How does a turbojet engine work?

Axial Turbojet; Air enters the engine and goes through a compressor, increasing the air's pressure and temperature. The air then enters the combustor where it is mixed with fuel and ignited. Next, the hot gas expands and spins the turbine which powers the compressor. Finally, the exhaust passes through a convergent nozzle into the atmosphere, creating a high velocity jet which pushes the aircraft. Centrifugal Turbojet; Nearly the same as an axial-flow turbojet, the centrifugal-flow turbojet compresses the air by diverting it from the axis of flow. While this type of jet is simpler, lighter and cheaper than axial-flow, it is less efficient and can not handle as high a volume of air. Often a combination of axial and centrifugal compressors are used in modern jets.


What is the difference between centrifugal and axial compressor?

Centrifugal compressors are more compact and simpler in design, but axial compressors are more efficient and better suited for high flow rate applications.


What is surging in compressor?

Centrifugal and axial compressors will surge when forward flow through the compressor can no longer be maintained, due to an increase in pressure across the compressor, and a momentary flow reversal occurs. Once surge occurs, the reversal of flow reduces the discharge pressure or increases the suction pressure, thus allowing forward flow to resume again until the pressure rise again reaches the surge point. This surge cycle will continue until some change is made in the process or compressor conditions.


What is the difference between axial in-line fans and centrifugal inline fans?

Axial fans are like a propeller - like most domestic fans. Centrifugal fans are like water or paddle wheeels that sit inside a case. Instead of water turning them, the wheel is driven by the motor and that moves the gas. In-line merely means that the fan sits in the gas flow.


Do you prefer a centrifugal compressor over a screw compressor?

Screw chiller running with a male & female blade,Centrifugual chiller running with an impeller. Screw chiller are very reliable on more load like more than 200 tr ,its less consumption comapare to other chillers.
