Well it's not modeled per se but speed does affect how you are detect, as does your depth. Keep it under 100 RPM's, closer to 50 , you are pretty quiet.Having silent running on will help.Depth plays in as it would at cavitation, example, I have been at 600 feet in a Balao running ahead standard at 6 knots and remained undetected by passive sonar of escorts 1800 yards away because I was deep, no cavitation there(O Kane mentions this in his book CLEAR THE BRIDGE)

Times when I was threading through and escort screen, I may go to 100 or 200 feet depending, silent running 100 rpms maybe more, depending on depth to slip inside the screen to attack.
