IGV position optimization for centrifugal blower

Experimental investigation on sound of a centrifugal blower and fluctuating pressure on its volute

The Research has shown that the primary sound source in centrifugal turbomachines is the blade passing frequency noise, which is caused by due to impac rotor exit flow with the volute and the wild pressure fluctuations. In this paper, a centrifugal blower with forward facing blades has been selected and the sound created by it in the output channel has been investigated in different operating c...

Educating the Whistle - Blower

Electric Blower Based Portable Ventilator

When a patient is unable to breathe or maintain their airway they will most likely be ventilated by a bag-valve-mask. We propose to replace the traditional bag-valve-mask with an electric blower ventilator. This handheld feedback controlled device will automatically compensate for mask leak and enable the clinician to deliver computer controlled respiratory rates and tidal volumes. We have buil...

Biochemical characterization of infantile gastroenteritis virus (IGV).

Enzymic and biophysical studies with purified infantile gastroenteritis virus (IGV) nucleic acid indicated that the virion contained a double-stranded RNA genome of approx. 14 x 10(6) daltons which could be separated by gel electrophoresis into eight bands of RNA which were comprised of 15 RNA species. Two major virus proteins, VP2 (mol. wt. = 135,000) and VP8 (mol. wt. = 40,000), which compose...

Spatial Optimization of Fertilizer Application by Centrifugal Spreading

We study an approach for the optimization of spreading performed by centrifugal spreaders in order to minimize environmental effects due to application errors. Faced with a large scale problem, we divide the domain of study into subdomains so that each tramline is individually dealt with. In order to take into account the mechanical limits of the device, some inequality constraints are introduc...
