Mathematical Model and Experimental Evaluation of Drag Torque in Disengaged Wet Clutches

Table 5

The relationship between the critical clutch speed and the relative magnitude of centrifugal force imposed onto the flow for different disks' rotational states.

Disks'; rotational state	Clutch speed	Relative; centrifugal force	Critical speed at which; drag torque peak occurs
OR	2𝜔	0.2𝜔^2	OR = 2.2ω ≈ 2ER
ER	0	𝜔^2	ER =ω
FS0	ω	0.3𝜔^2	FS0 = 1.82ω ≈ 2ER
