The corrosion caused by the action of chloride ions represents the greatest threat to the durability and service life of reinforced concrete structures. This pathological [...]

The article presents results of multicriteria design of airfoils suited for sailplanes. Airfoils for root and tip wing section as well as for empennage has been designed. [...]

It is shown that a system with counter-current in- and outflow (U-type flow) in heat exchangers can lead to an even distribution in branched systems with given high tempe [...]

This work contains the study of turbulent particle-laden channel flow, in which the particles experience a drag force. The method used for simulation of the liquid phase [...]

Use of ultra high strength concrete (UHSC) is effective in improving durability of concrete structures which should lead to establishment of sustainable society. However, [...]

The drag force acting on a spheroid moving perpendicularly to its axis of rotation in water was studied experimentally. Along the spheroid axis, which is normal to its ax [...]

In order to reduce the amount of CO2 gas in cement industry, the use of blended cement is valid. Share of blended cement in Japan, has not changed over last 10 years. One [...]

We have studied the influence of three cationic surfactants Arquad S50, CTAB and CTAC on three different types of local pressure drops. Experiments were done on a closed [...]

The age of micellar solution influences substantially effectiveness of drag reduction in a turbulent flow in tubes. In this contribution are shown effects of both surfact [...]
