High energy loss device
First Claim
1. A high energy loss fluid flow controlling device comprising:
- a plurality of members having aligned scalloped outer peripheries and being joined together into a rigid structure having a scalloped outer periphery continuously extending along the height of the rigid structure, said rigid structure having a series of high energy loss paths for fluid flow formed by said plurality of members;
inlet means centrally cut in each of said members according to a first geometrical configuration to define an inlet area for conducting fluid to the series of paths formed in said rigid structure by said plurality of members; and
scalloped outlet means formed along the entire scalloped outer periphery of said rigid structure to define a continuous scalloped outlet area along the entire height of said rigid structure.

Abstract
A more compact high energy loss device is provided having a series of uniquely formed multiturn labyrinth assemblies which reduce the pressure of a fluid flowing therethrough. The inlet of the labyrinth assemblies is formed according to a substantially circular configuration to have a predetermined inlet area while the outlet is formed according to a substantially scalloped configuration to provide an outlet area greater than the inlet area. The scalloped configuration of the outlet yields an outlet area which is also greater than if the outlet were of circular configuration. The scalloped outlet configuration also makes the labyrinth assembly less susceptible to circumferential thermal stresses resulting from high temperature fluids passing through the device producing high temperature inlet conditions and low temperature outlet conditions.

7. A device for providing high energy loss in fluids flowing therethrough comprising:
-
a rigid structure having a series of members joined together to have adjoining faces, each of said series of members having a central opening and a scalloped outer periphery, the central openings and scalloped outer peripheries of each member being aligned with each other in the rigid structure to provide a continuous central opening and a continuous scalloped outer periphery along the entire height of said rigid structure; a series of tortuous paths for fluid flow therealong being formed between at least a pair of the adjoining faces of said series of members between the central opening and the scalloped outer periphery of the rigid structure; inlet means formed in the aligned central opening of the rigid structure to provide an area for inleting fluid into said series of tortuous paths; and scalloped outlet means formed in the scalloped outer periphery of said rigid structure to provide an outlet area along the scalloped periphery of said rigid structure for exhausting fluid from said series of tortuous paths.
