A dynamic convergence control scheme for the solution of the radial equilibrium equation in through-flow analyses [PDF]
One of the most frequently encountered numerical problems in scientific analyses is the solution of non-linear equations. Often the analysis of complex phenomena falls beyond the range of applicability of the numerical methods available in the public ...

The share of technical thermoplastics is expected to grow further in the e‐mobility segment. In this study, a detailed temperature‐based tribological characterization of technical thermoplastics is performed. The tribological properties are discussed in terms of the dynamic mechanical properties of polymers at different ambient temperatures. A proof of

Experimental and model investigations of SPS casing treatment on a two-stage compressor
This paper will first carry out experimental investigations on a test compressor which is a large-scale, two-stage and low-speed axial one to evaluate the participation of a novel casing treatment (stall precursor-suppressed casing treatment, SPS CT ...

Effect of Blade Slot Positioning Close to Blade Root on the Performance of Highly Loaded Helium Compressor [PDF]
The helium compressor has the inherent characteristics of a lower single-stage pressure ratio and a higher number of stages than an air compressor. The highly loaded design method effectively addressed the compressibility issue of the helium compressor ...

A turbojet simulator for Mach numbers up to 2.0 [PDF]
A turbojet simulator was designed and fabricated for use in wind tunnel models. The simulator contains a six-stage, axial-flow compressor powered by a three-stage, axial-flow turbine. High pressure heated air was used to drive the turbine.

In this research, ZrC coatings are evaluated against various counterprobes at the microscale using novel super‐stiff atomic force microscopy cantilevers. The chemical composition of the coating is shown to be an important factor influencing coating hardness and Young's modulus, while surface roughness, counterprobe hardness, and surface energy are the ...
