A novel penalized wall function method for simulations of wall-bounded compressible turbulent flows is proposed. The new approach based on the Reynolds-averaged Navier–Stokes (RANS) equations to model outer region boundary layer, while inner part approximated by equilibrium model. differential formulation match external and solutions reformulated in a form generalized characteristic-based volum...

It is of value to determine the amount of viable myocardial tissue in patients suffering from chronic coronary artery disease and ventricular dysfunction. Having the capability of evaluating both myocardial perfusion and function, simultaneously, myocardial scanning by ECG-Gated is an appropriate method for this purpose. The aim of this study was to compare the results of myocardial perfu...

this study aimed to evaluate the effect of aerobic training with increased resistance of chest wall movement on ventilatory efficiency and pulmonary functions in untrained students. 18 untrained healthy male university students volunteered to participate in this study and were divided into two groups. they performed aerobic training with 70% – 80% of hrmax, three days a week for four weeks¬. ex...

background: diabetes mellitus is capable of impairing the myocardial function. several studies have documented the influential impact of diabetes mellitus on the left ventricular function. the right ventricular function plays a significant role in the overall myocardial contractility; hence, this study was undertaken to evaluate the effect of diabetes mellitus type ii on the right ventricular f...
