Relationship between optimum curved blade generate line and blade camber angle in linear compressor cascade

The relationship between the optimum curved blade generate line and blade camber angle in linear compressor cascade was researched by optimization method. Curved angle and curved height of curved blade generate line were optimized at eight different blade camber angles. The stack line was composed of two Bezier curves and a straight line, cascade loss decreases with the increasing curved height at the same curved angle, and the optimum curved height of the curved blade is 0.5. As for an optimum curved angle, at which curved blade total loss is minimal, curved blade loss decreases with increasing curved angle when curved angle is less than curved angle, and loss grows with increasing optimum curved angle when curved angle is larger than optimum curved angle. The benefits of the curved blade improve with increasing blade camber angle. Optimum curved angle increases along with the increasing blade camber angle. The relationship of optimum curved angle and blade camber angle presents a similar linear type.
