压力治疗用于治疗水肿和其它下肢静脉和淋巴疾病已经有数个世纪,其是简单下肢静脉溃疡的标准治疗方法。Laplace定律可以用于计算或估计绷带下压力(Sub-bandage pressure),即绷带向肢体施加的压力水平。本文将解释Laplace方程的建立,以及如何用其在临床实践中估算绷带下压力。 绷带所...
Fig. 9.4. Force vectors acting at the three-phase line of a liquid between infinite parallel plates. The constancy of curvature is a strong requirement: as explained above: if it is not, the Laplace pressure differences must cause flow to occur until equilibrium is reached (bearing in mind ...
Here, we present a microfluidic droplet trap that takes advantage of the net Laplace pressure force generated when a droplet is differentially constricted. Mathematical simulations were first used to understand the working range of the component; followed by finite element modeling using the CFD softwar...
Findings: Experiments confirm that the balance of external forces must be completed by the force acting on the syringe piston. The overpressure on the piston has an impact on the drops via the Laplace pressure. A master curve between the mean curvature and the maximal volume of the pendant dro...

The form of the law of Laplace most often used in hemodynamics gives the relation between transmural pressure and the stress in the wall in organs with a wall thickness h. We here use the Cauchy stress formulation, which is defined as the ratio of the normal (perpendicular) force acting on...

OurYoung-Laplace equation calculatorwill help you solve theYoung-Laplace equationfor a liquid in a column and determine itscapillary pressureandheight. You will never have difficulty solving the Laplace equation again! Capillary pressure can act as a driving force to transport liquid in a thin tube...
Using molecular dynamics (MD) simulations, a new approach based on the behavior of pressurized water out of a nanopore (1.3–2.7 nm) in a flat plate is developed to calculate the relationship between the water surface curvature and the pressure difference across water surface. It is found ...
