Acceleration of the Apex Seals in a Wankel Rotary Compressor Including Manufacturing Process Variation in Location of the Seals

Flow Seals Parameters Analysis For Rotors

The interaction of work fluid mechanics with that of the rotary system itself, basically composed of axes, bearings and rotors, is performed by inserting equivalent dynamic coefficients in the mathematical model of the rotor, the latter being obtained by the finite element method. In this paper, the dynamic coefficients of inertia, stiffness and damping of the flat seals analyzed here are evalu...

The Influence of Fluctuations in the Crankshaft Speed on the Tip Seal Acceleration of the Wankel Rotary Compressor

The acceleration of the tip seal in the rotor of a Wankel rotary compressor is a function of the radii of the fixed and moving pitch circles, the number of lobes, the trochoid ratio, and the speed and acceleration of.the crankshaft. The equations for the tip seal acceleration are well-known and have been used, in conjunction with the compression forces, to determine the spring forces that are n...

Computational fluid dynamics simulations for investigation of parameters affecting goaf gas distribution

It is necessary to obtain a fundamental understanding of the goaf gas flow patterns in longwall mine in order to develop optimum goaf gas drainage and spontaneous combustion (sponcom) management strategies. The best ventilation layout for a longwall underground mine should assist in goaf gas drainage and further reduce the risk of sponcom in the goaf. Further, in the longwall panel, regulators ...

Calculation of the Displacernent of a Wankel Rotary Compressor

The economic losses of small-scale fishers caused by Mediterranean monk seals, Monachus monachus (Hermann, 1779) in the Southern Aegean Sea: Muğla coasts

This study analyzed the interaction between the small-scale fishers and the Mediterranean Monk Seal (MMS) in an important Peninsula and two important marine protected areas on the southwest coast of Turkey. The survey was carried out from January 2014 to December in 2015 in the Muğla Province. Small-scale fishers in the study sites were interviewed to assess the interactions between small-scale...
