I don't know the name specifically, but in general if you need a very steep approach, for whatever reason, use full flaps, fly with the airspeed at the top of the white arc, and put the aircraft in a full-rudder sideslip. That maximizes the drag.
Note that with a full sideslip there's no guarantee that your ASI, ALT or V/S are accurate, so you might want to maintain a bit of margin below Vfe. (And well above Vs, obviously.) In general, you fly the aircraft more by feel, picture and wind noise than by instruments.
And note that certain aircraft, most notably some variants of the C172, do not permit slipping with flaps extended, due to the blanking of the tail assembly by the flaps.
