The admittance o• a turbulent jet as the generator in organ flue pipes was investigated experimentally with respect o the relevant parameters, that is, the frequency, the jet effiux velocity, the mouth end-correction, and the jet tip deflection at the cdge. First, an experiment was performed using a jet with a pulsating velocity to drive a pipe to isolate and identify the various drive mechanis...

A 59-year-old male patient presented with a pulsating mass at the left sternal edge weeks after a CABG procedure. CTshowed a false aneurysm of the LIMA (Fig. 1), confirmed by angiography (Fig. 2a). The leakage was treated using a 16-by-3.5-mm Jostent leading to complete lesion thrombosis (Fig. 2b). Fig. 1. Contrast enhanced CT shows a 6 cm diameter left internal mammary artery false aneurysm. F...

Depending on the spraying conditions and fluid properties, a variety of electrospray regimes exists. Here we explore the changes in ion production that accompany the transitions among the three axial spraying modes, the burst mode, the pulsating Taylor cone mode, and the cone-jet mode. Spray current oscillation and phase Doppler anemometry measurements, fast imaging of the electrified meniscus,...

With decrease in size of electronic equipment’s, effective heat removal is a major challenge these days. Present work focuses on implementation novel hybrid method which helps attain transfer enhancement. An experimental investigation carried out to study effect pulse air jet local distribution flat surface. Effect nozzle plate distance (z/d = 2 6), Reynolds number (5000 9000), pulsating freque...
