Properties of a well-defined Macroscopic Fundamental Diagram for urban traffic

Nikolaos Geroliminis

A field experiment in Yokohama (japan) revealed that a macroscopic fundamental diagram (MFD) linking space-mean flow, density and speed exists on a large urban area. It was observed that when the highly scattered plots of flow vs. density from individual f ...

Effect of Stators on the Performance and the Thermal Capabilities of Small Axial Cooling Fans

Peter Ott, Alexandros Terzis

This investigation examines experimentally the effect of stators on the performance curves and the heat transfer capabilities of small axial cooling fans. The experimental data indicated that the results are highly affected by the flow conditions at the fa ...

In-situ testing of a heat exchanger pile

Lyesse Laloui

The behavior of a pile subjected to thermo-mechanical loadings was studied in situ with the aim of quantifying the thermal influence on the bearing capacity of heat exchanger piles. A pile situated in a building under construction was equipped with a chann ...

Multistage hydraulic gas compression/expansion systems and methods

Alfred Rufer

Multistage hydraulic systems and methods for converting the potential energy of a pressurized gas, particularly air, into mechanical work operating in motor, and for producing compressed gas from the mechanical work of the rotating shaft (A1.1 ) when rotat ...

Flow pattern based two-phase frictional pressure drop model for horizontal tubes. Part I: Diabatic and adiabatic experimental study

John Richard Thome, Jesus Moreno Quiben

The reliable prediction of pressure drop in two-phase flow is an important prerequisite to accurate optimization of thermal systems. Because of the complexity of these types of flow, empirical or semiempirical relationships are only of limited reliability ...

Optimization of a Single Phase Ultrasonic Linear Motor

Yves Perriard, José Fernandez Lopez, Markus Flückiger

Piezoelectric ultrasonic motors are superior to electromagnetic micromotors, because their efficiency remains theoretically constant during miniaturization. However, the still relatively recent technology has a considerable unexploited optimization potenti ...
