Apertured-disk mixer

A fluid handling device, comprising:

• a housing having a first end, a second end, and a side enclosing an interior space, at least one fluid port communicating with said interior space, said housing further having an inner surface bounding said interior and a substantially uniform cross-section for at least a portion of the length of said side;
• a plurality of first plates, each of said first plates having a first side, a second side and a periphery having a plurality of extreme points and segments between said extreme points, said extreme points and said segments between said extreme points defining a shape wherein said extreme points of each of said first plates contacts said inner surface of said housing and further wherein said segments between said extreme points define gaps between said periphery and said inner surface of said housing, each of said first plates further having a plurality of projections extending from at least one of said first side and said second side;
• a plurality of second plates, each of said second plates having a first side, a second side and a periphery, said periphery defining a shape substantially approximating said cross-section of said housing wherein said periphery of each of said second plates contacts said inner surface of said housing without substantial gaps between said periphery and said inner surface of said housing, each of said second plates further having at least one aperture between said first side and said second side and each of said second plates having a plurality of projections extending from at least one of said first side and said second side;
• wherein said first plates and said second plates alternate positions throughout at least a portion of said length of said housing having said uniform cross-section;
• and
• wherein each of said first and said second plates further comprises means for interlockinig said plates together and means for rotating said interlocking plates within said housing.
