And Performance

An unconventional type of turbomachinery employing a rotor composed of smooth disks is described and the history and motive principle of such devices are briefly discussed. Several experimental multiple-disk air turbines are described and data showing the performance and efficiency of the turbines are presented. A mathematical model of a multiple-disk turbine is described. The equations of motion are written for the flow of an incompressible fluid between the disks, and parameters describing the efficiency and performance of the turbine, in the absence of losses external to the rotor, are derived. The solution for the equation of motion and the performance parameters, obtained by computation with an IBM 704, are summarized, discussed, and referenced. The results indicate that multiple-disk turbines may be attractive in the low-power part of the turbine spectrum, or where first cost is a prime factor, or where the properties of the working fluid cause conventional turbines to be inadequate.

A novel heat exchanger for automotive applications developed by the Heat Transfer and Fluid Flow Laboratory at the Brno University of Technology, Czech Republic, is compared with a conventional commercially available metal radiator. The heat transfer surface of this heat exchanger is composed of polymeric hollow fibers made from polyamide 612 by DuPont (Zytel LC6159). The cross-section of the polymeric radiator is identical to the aluminum radiator (louvered fins on flat tubes) in a Skoda Octavia and measures 720 × 480 mm. The goal of the study is to compare the functionality and performance parameters of both radiators based on the results of tests in a calibrated air wind tunnel. During testing, both heat exchangers were tested in conventional conditions used for car radiators with different air flow and coolant (50% ethylene glycol) rates. The polymeric hollow fiber heat exchanger demonstrated about 20% higher thermal performance for the same air flow. The efficiency of the polymeric radiator was in the range 80–93% and the efficiency of the aluminum radiator was in the range 64–84%. The polymeric radiator is 30% lighter than its conventional metal competitor. Both tested radiators had very similar pressure loss on the liquid side, but the polymeric radiator featured higher air pressure loss.
