Selected empirical correlations.

	Loss coefficient	Deviation angle
Forward, unstalled flow	Reference loss coefficient: Koch and Smith model	Reference deviation angle: Lieblein method [13]
	Off-design loss coefficient: Creveling model [14]	Off-design deviation angle: Lieblein model [13]
Stalled flow	Moses and Thomason modified loss model [15, 16]	Tauveron deviation angle model [12]
Reversed flow	Longley modified loss model [12, 17]	Exit flow parallel to the stagger direction
