As a domain expert in engineering and thermodynamics, I can explain the term "V Q mismatch" in the context of power plant operations, particularly in combined cycle power plants.
V Q mismatch refers to a condition where the volumetric flow rate (V) of the working fluid in a gas turbine does not match the heat input (Q) into the system. This mismatch can lead to several issues, such as:
1. Thermal Stress: If the heat input is too high for the volume of fluid, it can cause thermal stress on the turbine blades and other components.
2. Efficiency Reduction: A mismatch can also lead to a decrease in the overall efficiency of the power plant, as the turbine may not be operating at its optimal design point.
3. Output Fluctuations: It can cause fluctuations in the output power of the plant, affecting its reliability and stability.
To manage a V Q mismatch, operators may need to adjust the fuel flow, steam flow, or other parameters to ensure that the system operates within safe and efficient limits.

In respiratory physiology, the ventilation/perfusion ratio (V?/Q? ratio or V/Q ratio) is a ratio used to assess the efficiency and adequacy of the matching of two variables: V? or V �� ventilation �� the air that reaches the alveoli. Q? or Q �� perfusion �� the blood that reaches the alveoli via the capillaries.
