Increasing the Power of the α-Type Stirling Engine by Changing Mutual Orientation of Compression and Expansion Cylinders

  • K. O. Sabdenov

摘要

The power of a V-shaped α-type Stirling engine can be increased greatly by decreasing the angle Δψ between the cylinders of the heater and cooler. This occurs due to the tendency to zero of the phase difference between the oscillations of their pistons. Together with the decrease in the angle Δψ, the coefficient of hydraulic resistance of the regenerator KΣ also decreases. An increase in the angle Δψ leads to the appearance of a critical value of KΣ, when the engine stops working.
