EFFECT OF CYLINDER DIAMETER ON STATE QUANTITIES FOR IRREVERSIBLE PROCESS IN PISTON-CYLINDER SYSTEM

Effect of time-dependent piston velocity program on vortex ring formation in a piston/cylinder arrangement

An analytical model describing laminar vortex ring formation in a nozzle flow generator piston/ cylinder arrangement proposed previously by the authors is extended to time-dependent velocity programs. The predictions of the model are in good agreement with the available numerical data for impulsive, linear, and trapezoidal velocity programs. We also show that properly scaled vortex circulation ...

Diameter of a set on the cylinder

We present an algorithm that computes the diameter of a set of n points in the cylinder in optimal time O(n log n); this algorithm uses as a fundamental tool the farthest point Voronoi diagram.

State of Practice for Concrete Cylinder Match Curing and Effect of Test Cylinder Size

To Improve the Performance of a Refrigeration Compressor by Optimizing Piston Stroke and Cylinder Diameter

During the operation of a refrigeration compressor, electric power is transported from electric source to the refrigerant. Since there is a large amount of power required for the operation, it is necessary to save energy through the performance improvement. For this purpose, mathematical models consisting of nonlinear ordinary differential and algebraic equations are developed and applied for t...

Primary pressure standards based on dimensionally characterized piston/cylinder assemblies

NIST has characterized two large diameter (35.8 mm) piston/cylinder assemblies as primary pressure standards in the range 0.05 MPa to 1.0 MPa with uncertainties approaching the best mercury manometers. The realizations of the artefacts as primary standards are based on the dimensional characterization of the piston and cylinder, and models of the normal and shear forces on the base and flanks o...
