In fluid mechanics, the Rayleigh–Plesset equation or Besant–Rayleigh–Plesset equation is an ordinary differential equation which governs the dynamics of a spherical bubble in an infinite body of incompressible fluid. Its general form is usually written aswhere See more Neglecting surface tension and viscosity, the equation was first derived by W. H. Besant in his 1859 book with the problem statement stated as An infinite mass of homogenous incompressible fluid acted upon by no forces is … See more More recently, analytical closed-form solutions were found for the Rayleigh–Plesset equation for both an empty and gas-filled … See more The Rayleigh–Plesset equation can be derived entirely from first principles using the bubble radius as the dynamic parameter. Consider a spherical bubble with time-dependent radius $${\displaystyle R(t)}$$, where $${\displaystyle t}$$ is … See more Webbody of liquid. The Rayleigh-Plesset equation is derived from the Navier-Stokes equations under the assumption of spherical symmetry. Neglecting surface tension and viscosity, the equation was rst derived by John Strutt, 3rd Baron Rayleigh in 1917. The equation was rst applied to traveling cavitation bubbles by Milton S. Plesset in 1949. WebRayleigh–Plesset equation是一个模拟流体中空心泡运动的常微分方程。 small desk with cabinet
