Aerodynamic loading acting on the stator vane in the variable nozzle turbine flow

The purpose of this paper is to evaluate an aerodynamic loading acting on the stator vanes of the turbocharger using variable nozzle turbine (VNT). Computational fluid dynamic (CFD) is applied using commercial software ANSYS CFX. A full turbine stage CFD model is used t...

Wall heat transfer in gas-fired furnaces: Effect of radiation modelling

The purpose of this work is to study heat transfer to cooled walls in a MW-scale laboratory furnace with a dominating thermal radiation component. Experiment is performed in a specially designed combustion chamb...

Optimization of plated steel beams using metamodels and modern optimization methods

This paper deals with metamodel-based optimization of plated steel beams. The first part of the article explains the principle of the metamodel-based optimization approach and also provides basic information on incorporated sub-methods such as design of experiments (DOE), math ematic...

Frontal impact response of a virtual low percentile six years old human thorax developed by automatic down-scaling

Traffic accidents cause one of the highest numbers of severe injuries in thewhole population spectrum. The numbers of deaths and seriously injured citizens prove that traffic accidents and their consequences are still a serious problem to be solved. The paper contributes to ...

Blade couple with dry friction connection

Vibration of a blade couple damped by a dry friction contact in the shroud is investigated by means of hysteresis loops and response curves analysis. The studied system is excited by one harmonic external force in a frequency range near to the lowest eigenfrequency ...

Modelling of flexi-coil springs with rubber-metal pads in a locomotive running gear

Nowadays, flexi-coil springs are commonly used in the secondary suspension stage of railway vehicles. Lateral stiffness of these springs is influenced by means of their design parameters (number of coils, height, mean diameter of coils, wire diameter etc.) and it is often su...

Evaluation of human thorax FE model in various impact scenarios

The study focused on the validation of the 50 th percentile male model — a detailed FE model of the thoracic segment of the human body developed within project Development of a Finite Element Model of the Human Thorax and Upper Extremities (THOMO)...
