Abstract
An analysis was made of pressure and flow in a novel elastic tube system which has been used to theorize certain aspects of renal hemodynamic cs. Validation of the theory could alter the treatment of certain heart and kidney disorders. In an attempt to better understand a system flow anomaly under steady driving head conditions, experiments were performed, and a mathematical model was developed. The development of the model incorporated a set of nonlinear differential and algebraic equations. Using a finite-difference analysis as the method for obtaining a numerical solution, various pressures and flows were obtained. Results for the steady-state model were validated by a series of experiments. The results of the model revealed that the largest contributing factor to the nonlinear characteristics of the flows and pressures was due to the distensible tube walls that made up the experiment and the model. The response of the system to instantaneous changes in the loop exit venturi throat diameter was of the order of milliseconds. This response time was due to the controlling nature of the loop/corset elements in the model.
