V-Notch Weir Overflow: an Unsteady Calibration
Thin-plate V-notch weirs are commonly used as measuring devices in flumes and channels. Herein, the discharge calibration of a large 90o V-notch weir was performed using an unsteady volume per time technique. The weir overflow was initially shut. The sudden opening of the gate was associated with an initial phase of transient water motion associated with a negative wave propagating in the reser...
متن کاملNonlocal Vibration of Y-SWCNT Conveying Fluid Considering a General Nonlocal Elastic Medium
In this paper, a nonlocal foundation model is proposed to analyze the vibration and instability of a Y-shaped single-walled carbon nanotube (Y-SWCNT) conveying fluid. In order to achieve more accurate results, fourth order beam theory is utilized to obtain strain-displacement relations. For the first time, a nonlocal model is presented based on nonlocal elasticity and the effects of nonlocal fo...
متن کاملFluid-structure Interaction Vibration Analysis of Vertical Cylindrical Containers with Elastic Bottom Plate Made of Functionally Graded Materials
In the present paper a method is proposed to investigate the free vibration of a partially liquid-filled cylindrical tank. The mechanical properties of the container are assumed to change continuously along the thickness according to volume fraction Power-law, Sigmoid or Exponential distribution. The liquid is supposed to be incompressible and in viscid and its velocity potential is formulated ...
متن کاملUrinary incontinence: a vibration alert system for detecting pad overflow.
A sensor and electronics system is described that monitors the leakage of urine from continence pads into surrounding underwear. Urinary incontinence is involuntary loss of urine and occurs when the bladder muscles contract without warning or the sphincter muscles surrounding the urethra are too weak to prevent leakage. The system comprises a wetness sensor and electronics unit. The sensor is s...
متن کاملActive Vibration Suppression of a Nonlinear Flexible Spacecraft
In this article, the issue of attitude control and active vibration suppression of a nonlinear flexible spacecraft is assessed through piezoelectric patches as actuator and sensors. Two controller loops are applied: the inner loop, to make the panel vibration damped through piezoelectric patches; and the outer loop, to perform spacecraft maneuver using the reaction wheel acting on the hub. An o...
