Fluid systems and methods that address flow separation

A fluid system for addressing flow separation having a first end and a second end, the fluid system comprising:

• a main body having a first end, a second end, a lengthwise axis, a first portion, a second portion, an injection opening, a suction opening, a channel, a side wall, a first opening at the first end of the main body, a second opening at the second end of the main body, and a passageway extending from the first opening to the second opening;
• the first portion disposed between the first end of the main body and the second end of the main body, the second portion extending from the first portion toward the second end of the main body, the first portion having a first axis extending along the side wall, the second portion having a second axis extending along the side wall at an angle relative to the first axis such that when fluid flows over the main body said flow separation is defined adjacent to the second portion;
• the injection opening disposed between the first opening and the second opening and at a first location relative to said flow separation, the injection opening partially extending around the lengthwise axis and the passageway;
• the suction opening disposed between the injection opening and the second opening and at a second location relative to said flow separation, the suction opening partially extending around the lengthwise axis and the passageway;
• the channel extending from the suction opening to the injection opening;
• and
• a fluid pressurizer disposed within the channel and moveable between on and off states such that fluid flows into the suction opening and out of the injection opening when the fluid pressurizer is in the on state.
