the engine is having high pressure inside the combustion chamber.the flow has to move trough nozzle.incase the pressure is very high at nozzle compared to the intake pressure the flow moves forward.then the compressors shape changed it is not enough to compress the intake air.it is compressor stall
If you are referring to a gas turbine generator (i.e. an aircraft jet engine), a stall is associated with the compressor blades. Compressor blades are simply little wings (airfoils) and when the air enters the engine in an incorrect fashion (such as a strong cross wind or a birdstrike), the air does not flow over the blades as designed and can separate. This separation can be severe enough to cause the compressor to loss the ability to compress air and supply high pressure air to the combustion chambers.
The loss of the high pressure air allows the high pressure air from the combustion chamber to exit through the compressor in something called a compressor surge. The surge can be very violent and cause structural damage to blades, casing and the shaft. A compressor surge is shown in the following video just to demonstrate how an engine reacts in a compressor surge:

How inefficiencies of compressor and turbine affect back work ratio and efficiency of gas turbine?
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.
What is a CIT sensor?
Compressor Inlet Temperature sensorfor a Gas turbine engine.
What is intermediate pressure turbine?
Some varieties of gas turbine engines (e.g. RR Trent and RB211) have 3 concentric rotating shafts. Each shaft connects a compressor with a turbine. The low pressure compressor, or fan, is driven by the low pressure turbine. The high pressure compressor is driven by the high pressure turbine. Between the low and high pressure compressors there is an intermediate pressure compressor and, guess what... it's driven by the intermediate pressure turbine.
The function of a gas turbine compressor?
The compressor on a gas turbine and other jet engine types takes the air around us at normal pressures, and compresses it to much higher pressures and temperatures. Like the compression stroke on a internal combustion engine, the incoming air needs to be at extreeme pressures for the engine to be efficient.
What is the function of the Turbine Section of the Industrial Gas Turbine?
It does a number of things depending on what type of engine its coming from, but in all engines, it extracts energy from the combustion gasses and turns the shaft which also turns the compressor section.
How inefficiencies of compressor and turbine affect back work ratio and efficiency of gas turbine?
Inefficiencies in the compressor of a gas turbine cycle increase the back-work ratio and decrease the thermal efficiency of the gas turbine cycle, since they increase the compressor work.
What is gas turbine compressor pulsation?
GT compressor pulsation ?
Which type of rotary compressor used in gas turbine?
Rotating axial compressor.
What is gas turbine pulsation?
GT compressor pulsation ?
How much energy air compressor alone consumes in the energy generated by a gas turbine?
Air compressor alone consumes about 50 to 60 % of energy generated by a gas turbine..
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 is the self-sustaining speed of gas turbine?
self sustaining speed is output of a turbine= input into compressor
What is a CIT sensor?
Compressor Inlet Temperature sensorfor a Gas turbine engine.
Why is compressor required in a gas turbine?
because anyone can cause you a prodigal son
What is stalling in compressor?
Damage of the blades of the compressor ,cauesd due high angles of pressure ,caused by air flow is called stalling of a compressor
What are the types of stator?
the types of statore are compressor, gas turbine, turboprop, and jet engine
