What is tHe purpose of inlet guide vanes in gas turbine?

In axial flow compressors, the primary purpose of IGVs (fixed or variable) is to guide the airflow onto the first stage rotor blades at an appropriate or required angle of attack.


Is rotary screw type compressor is mass flow compressor?

A rotary screw compressor is not typically categorized as a mass flow compressor. It is a type of positive displacement compressor that works by trapping a volume of air and reducing its volume to increase pressure. Mass flow compressors, like centrifugal compressors, are dynamic machines that rely on the mass flow rate of the gas to develop pressure. Rotary screw compressors are ideal for applications requiring continuous air supply, known for efficiency, reliability, and low noise. For high-quality rotary screw compressors, visit MasterAire.

What is difference between radial flow turbine and axial flow turbine?

in a radial flow turbine the steam enters the turbine in the direction of its radius and leaves it in the direction of the axis of the shaft. in a axial flow turbine the steam enters the turbine in the direction of the axis of the shaft and leaves the turbine in the same direction.


Disadvantages of centrifugal compressor in gas turbine?

This relationship is the reason advances in turbines and axial compressors often find their way cutaway showing an axi-centrifugal compressor gas turbine.


What are application of rotary screw compressors?

Rotary screw compressors are used in many industrial compressed air systems due to the high volume they produce in comparison to reciprocating compressors. Rotary screws take up much less space, require no heavy flywheels, and need less maintenance than the recip. compressors. Oil free compressed air can be produced by large rotary screw compressors designed as such, while reciprocating compressors can do this only on a smaller scale due to the need for cylinder lubrication in the larger models.

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.

What is the difference of an axial flow and centrifugal compressor?

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.


Axial flow turbomachines?

These are machines dealing with fluids, like (Axial Compressors, pumps and Fans). the term "Axial" is given due to the direction of inward and outward flow. In axial turbo machines the direction of outward flow is the same as the direction of the inward flow since the blades of the machines doesn't change the direction of flow.


What is the difference between centrifugal and axial compressor?

*Axial compressors are rotating, aerofoil based compressors in which the working fluid principally flows parallel to the axis of rotation. This is in contrast with centrifugal, axi-centrifugal and mixed-flow compressors where the air may enter axially but will have a significant radial component on exit. *Axial flow compressors produce a continuous flow of compressed gas, and have the benefits of high efficiencies and large mass flow capacity, particularly in relation to their cross-section. They do, however, require several rows of aerofoils to achieve large pressure rises making them complex and expensive relative to other designs (e.g. centrifugal compressor). *Centrifugal fan/blowers are more suited to continuous-duty applications such as ventilation fans, air movers, cooling units, and other uses that require high volume with little or no pressure increase. In contrast, multi-stage reciprocating compressors often achieve discharge pressures of 8,000 to 10,000 psi (59 MPa to 69MPa). One example of an application of centrifugal compressors is their use in re-injecting natural gas back into oil fields to increase oil production. Centrifugal compressors are often used in small gas turbine engines like APUs (auxiliary power units) and smaller aircraft gas turbines. A significant reason for this is that with current technology, the equivalent flow axial compressor will be less efficient due primarily to a combination of rotor and variable stator tip-clearance losses. There are few single stage centrifugal compressors capable of pressure-ratios over 10:1, due to stress considerations which severely limit the compressor's safety, durability and life expectancy. *Compressor section location depends on the type of compressor. In the centrifugal-flow engine the compressor is between the accessory section and the combustion section; in the axial-flow engine the compressor is between the air inlet duct and the combustion section. *Centrifugal-flow compressors have the following advantages: * High pressure rise per stage. * Efficiency over wide rotational speed range. * Simplicity of manufacture with resulting low cost. * Low weight. * Low starting power requirements. They have the following disadvantages: * Large frontal area for given airflow. * Impracticality if more than two stages because of losses in turns between stages. **Axial-flow compressors have the following advantages: * High peak efficiency. * Small frontal area forgiven airflow. * Straight-through flow, allowing high ram efficiency. * Increased pressure rise due to increased number of stages with negligible losses. They have the following disadvantages: * Good efficiency over narrow rotational speed range. * Difficulty of manufacture and high cost. * Relatively high weight. * High starting power requirements (this has been partially overcome by split compressors).

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.

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.
