US Patent:

20050114097, May 26, 2005

Filed:

Sep 13, 2004

Appl. No.:

10/939802

Inventors:

Bradley Duncan - Huntersville NC, US

Assignee:

Automotive Aerodynamics, Inc. - Cornelius NC

International Classification:

G06F017/50

US Classification:

703001000

Abstract:

A method for analyzing a turbulent fluid flow field includes the steps of: creating a mathematical model of a physical object; simulating a flow field around said model, wherein said flow field is at least partially turbulent; generating time series flow data output data representative of said flow field; and identifying repeating turbulent flow patterns in said flow data. These features are identified by selecting at least one frequency range of interest; filtering the flow data based on the frequency range; and observing coherent structure in the filtered data. The method may be implemented as a software program running on a computer.

16/864522

Inventors:

- Cambridge MA, US
Bradley P. Duncan - Andover MA, US

International Classification:

B29C 64/165
B29C 64/209

Abstract:

A 3-D printed device comprising one or more structures, the structures comprising a plurality of magnetically responsive particles and one or more diblock or triblock copolymers; the diblock or triblock copolymers having an A-B, A-B-A, or A-B-C block-type structure in which the A-blocks and C-blocks are an aromatic-based polymer or an acrylate-based polymer and the B-blocks are an aliphatic-based polymer. These 3-D printed devices may be formed using a method that comprises providing a magnetic ink composition; applying the magnetic ink composition to a substrate in a 3-D solvent cast printing process to form one or more structures; and drying the one or more structures formed from the magnetic ink composition. The dried structures can exhibit one or more regions of magnetic permeability greater than 1.3×10H/m.
