Karman vortex street at Re = 80
Переглядів 8 тис.2 роки тому
Calculation of the Kármán vortex street for the two-dimensional flow around an infinite cylinder, with Re = 80. The calculation uses a stream function-vorticity formulation and a second order finite difference method in log-polar coordinates. The spatial resolution is 401x402 grid points. The vorticity equation is integrated in time using the MATLAB function ode23.m. Massless particles one grid...

    ¿se produce ese desfasaje porque las direncias mumericas leves de discretizacion de la mallas entre distintos puntos se va acentuando a medida que que se itera? y esta diferencia existe en los errores geometricos de los cilindro como minimas asimetrias reales que induces a generas las semillas de las oscilaciones? pero esto no es la explicacion de esto en si, ¿porque debe usarse con Navier Stokes como una receta aspirina para todo tipo de dolor sin ir al medico? ¿realmente esa ecuacion es valida para usarse en estos casos?, A mi juicio se ignoran otros fenomenos para entender este problema, porque se quiere seguir alguna escuela de pensamiento o teoria de fisica

    Hi thanks for the video ! I just have a question related to the probabilities B x delta t and Gamma x Delta t. If I understand correctly it makes the asumption that the probability that an infective infects a susceptible in a time delta t is proportional to that time delta t. Which would mean the probability would go over 1 in a long time stretch which is impossible. I'm using this model for my final school presentation and I need to be ready to answer these questions :)
