WebApr 1, 2009 · Particle motion in an unsteady peristaltic fluid flow is analyzed. The fluid is incompressible and Newtonian in a two-dimensional planar geometry. A perturbation method based on a small ratio of wave height to wavelength is used to obtain a closed-form solution for the fluid velocity field. This analytical solution is used in conjunction with an … Web119K views 9 years ago Peristaltic waves, as observed in this infant, are one of the classic signs associated with pyloric stenosis.

WebJun 28, 2024 · The peristalsis is therefore characterized as a wavelike movement inside flexible tubes triggered and operated by a physiological flexion and extension of adjacent locations, which leads to a movement of the within contents. In medicine, the fluid wave test or fluid thrill test is a test for ascites (free fluid in the peritoneal cavity). It is performed by having the patient (or a colleague) push their hands down on the midline of the abdomen. The examiner then taps one flank, while feeling on the other flank for the tap. The pressure on the midline prevents vibrations through the abdominal wall while the fluid allows the tap to be felt on the other side. The result is considered positive if tap can be felt on t…
