Publication number: 20230175920Abstract: A method for predicting if a flow over a smooth ramp surface will separate from the ramp surface, wherein the ramp surface has a slope that is everywhere non-positive along the length of the ramp surface relative to the flow at the inflow end of the ramp surface includes i) dividing the height of the ramp surface by the length of the ramp surface to determine a height-to-length ratio of the ramp surface, ii) identifying a maximum slope magnitude of the ramp surface, iii) calculating a maximum normalized slope by dividing the maximum slope magnitude of the ramp surface by the height-to-length ratio of the ramp surface, and calculating a critical ramp slope as a linear function of the height-to-length ratio of the ramp surface. If the maximum normalized slope is greater than the critical ramp slope, the method predicts the turbulent boundary layer will separate from the ramp surface.Type: ApplicationFiled: May 18, 2021Publication date: June 8, 2023Applicant: UNIVERSITY OF WASHINGTONInventors: Antonino Ferrante, Abhiram Aithal, Dawei Lu

Patent number: 11665310Abstract: An electronic device has pixels that form an active area of a display for displaying images for a user. A layer of black ink or other opaque material may be formed on an inner surface of a display cover layer in an inactive area of the display that does not overlap pixels. The housing may have sidewalls such as a rear housing wall that faces away from the display. Ambient light sensor windows may be formed from tapered holes or other holes. The tapered holes may be formed in the opaque material on the display cover layer, may be formed in a rear housing wall or other hosing structure, or may be formed in other portions of the electronic device. Non-tapered holes may also form windows. Tapered holes may have sidewalls with portions that run parallel to their longitudinal axes and portions that are angled relative to their longitudinal axes.Type: GrantFiled: March 9, 2022Date of Patent: May 30, 2023Assignee: Apple Inc.Inventors: Dawei Lu, Kenneth J.
