Showing papers on "Throughflow published in 1982"
TL;DR: In this article, the contribution of throughflow to storm runoff was examined using a chemical mixing model and the results predict that throughflow is an important component of storm runoff particularly during the period of stream recession.
Abstract: The contribution of throughflow to storm runoff is examined using a chemical mixing model. The results predict that throughflow is an important component of storm runoff particularly during the period of stream recession. Supporting hydrological data suggests that a major throughflow input occurs coincident with the stream discharge peak. The two sets of results therefore conflict in the predicted timing of the throughflow response.

TL;DR: In this paper, the authors describe a lapping or polishing machine, where for cooling a plurality of zones of its working face the tool comprises for each of these zones separate supply conduits for fluids at different temperatures and/or rates of throughflow, and there are also provided temperature sensing means with an apparatus for controlling the temperature or rate of the fluid.

TL;DR: In this paper, a reliable method is presented for calculating the flowfield about a cascade of arbitrary two-dimensional airfoils. But this method is not suitable for turbomachinery blade rows.
Abstract: A reliable method is presented for calculating the flowfield about a cascade of arbitrary two-dimensional airfoils. The method approximates the three-dimensional flow in a turbomachinery blade row by correcting for streamtube convergence and radius change in the throughflow direction. 12 refs.

TL;DR: In this paper, coal is pretreated for a coking plant so that it is passed in two stages through two throughflow driers successively connected with one another, the driers are supplied with a heat carrier formed by a steam overheated to a temperature between 400° and 600° C.
Abstract: Coal is pretreated for a coking plant so that it is passed in two stages through two throughflow driers successively connected with one another, the driers are supplied with a heat carrier formed by a steam overheated to a temperature between 400° and 600° C., dust is removed from the steam after passing the throughflow driers, and the steam is heated after the dust removal in a heat exchange with a circulating gas of a coke dry cooler.

TL;DR: In this article, a process and an arrangement for measuring of the throughflow in a gas or liquid stream are described, which are distinguished in that at least two measurement sensors, arranged one behind the other in the direction of flow, scan a vortex street and, apart from the vortex frequency information, a further additional item of information is evaluated, preferably the phase position of the output signals of the measurement sensors or the time taken for one vortex to pass from one measurement sensor to the other.

TL;DR: In this article, a multi-plate water-cooled oil cooler has a pack (5) of double-walled plates and flow guides are provided in the form of outwardly stamped configurations.
Abstract: A multi-plate water-cooled oil cooler has a pack (5) of double-walled plates (11). in the gap (16) between adjacent plates flow guides are provided in the form of outwardly stamped configurations (20,21) which improve the flow in the gap (16), so as to achieve more even throughflow over the entire cross- section and enhanced cooling efficiency.

TL;DR: In this article, a process for measuring the throughflow in a fluid stream, in which fluidic oscillations are produced in the stream and in which a physical parameter which is representative of the oscillation frequency is experimentally determined as the measured signal from at least two measuring points, is described.
Abstract: A process for measuring the throughflow in a fluid stream, in which fluidic oscillations are produced in the stream and in which a physical parameter which is representative of the oscillation frequency is experimentally determined as the measured signal from at least two measuring points, and which is distinguished in that, after establishing disturbance-free reference parameters, measurement signals from several measuring points are first separately processed and are then combined with one another and compared with the reference parameters.
