## Abstract For the construction of the longest rail tunnel in the world, the selection of the optimal method of tunnelling was of considerable importance. Not only the ground properties were decisive for the decision but also other constraints, like for example the environmental requirements or th
The criteria as well as the methods and measurements of wind tunnel simulation on wind effects on air-cooled condensers in a power plant were discussed. The parameter of recirculation was suggested to describe the wind effects on the efficiency of the condenser. The result of practical project model
Cause of Weakness in the St. Gothard Tunnel.--Investigations have been made of tile cause of weakness in the parts of the St. Gothard tunnel where the vaults were crushed, and it is thought that the accident must be attributed to the action of damp air upon the schists and gneiss, and to the decompo
## Abstract The internal circulation and the shape of water drops falling at terminal velocity in air of 20Β°C at sea level pressure, and nearly water saturated, were studied by means of a wind tunnel. Drops with an equivalent radius a~0~ smaller than 140 ΓΌm had within the experimental error no dete
