In gas turbine
is there a relationship between air mass flow and igv angle
and what is the air flow value at minimum igv angle (fully closed)?

Question

Anuj Johri · Answer

The value of air flow depends on the size of turbine, however the air flow is minimum at IGV fully closed position.

Muhammad Nadeem · Answer

depends on igv types & operating system of igv Manually or automatic change its angle

and compressor capacity

olusegun akinmutimi · Answer

The volume of inflow air mass depend majorly on the rate and angle at which igv open. The air inflow at minimum igv angle is zero.

Adnan Abu Irshed · Answer

with the increased igv angle the air flow increases the min angle is at turning gear or rotor baring and the air flow is zero
