Oscillations of a solid sphere falling through a wormlike micellar fluid
Anandhan Jayaraman, Andrew Belmonte
We present an experimental study of the motion of a solid sphere falling through a wormlike micellar fluid. While smaller or lighter spheres quickly reach a terminal velocity, larg…
Monotone Solutions of a Nonautonomous Differential Equation for a Sedimenting Sphere
Jon Jacobsen, Anandhan Jayaraman, Andrew Belmonte
We study a class of integrodifferential equations and related ordinary differential equations for the initial value problem of a rigid sphere falling through an infinite fluid medi…
First Principles Justification of a ``Single Wave Model'' for Electrostatic Instabilities
John David Crawford, Anandhan Jayaraman
The nonlinear evolution of a unstable electrostatic wave is considered for a multi-species Vlasov plasma. From the singularity structure of the associated amplitude expansions, the…
Amplitude Equations for Electrostatic Waves: multiple species
John David Crawford, Anandhan Jayaraman
The amplitude equation for an unstable electrostatic wave is analyzed using an expansion in the mode amplitude . In the limit of weak instability, i.e. where i…
Nonlinear saturation of electrostatic waves: mobile ions modify trapping scaling
John David Crawford, Anandhan Jayaraman
The amplitude equation for an unstable electrostatic wave in a multi-species Vlasov plasma has been derived. The dynamics of the mode amplitude is studied using an expansion…
