AbstractAbstract
[en] A cooling tower is described where water runs over packing plates being cooled by steaming air. In the cooling process a combination of wet and dry cooling is applied, namely by special design of the packing plates which are arranged inclined to the vertical. Spraying device and packing plates are shaped in such a way that the plates are wetted almost on one side only. 13 drawings explain the construction of the device described in detail. (UWI)

Es wird ein Kuehlturm beschrieben, bei dem Wasser ueber Rieselplatten laeuft und durch stroemende Luft abgekuehlt wird. Beim Kuehlverfahren wird eine Kombination Nass-Trockenkuehlung angewandt, und zwar durch besondere Ausgestaltung der Rieselplatten, die zur Vertikalen geneigt angeordnet sind. Spruehvorrichtung und Rieselplatten sind so ausgebildet, dass die Rieselplatten fast nur einseitig benetzt werden. 13 Zeichungen verdeutlichen den ausfuehrlich beschriebenen Aufbau der Vorrichtung.

AbstractAbstract
[en] This project has been focused on the experimental and numerical investigations of the water-cooled and air-cooled Reactor Cavity Cooling System (RCCS) designs. At this aim, we have leveraged an existing experimental facility at the University of Wisconsin-Madison (UW), and we have designed and built a separate effect test facility at the University of Michigan. The experimental facility at UW has underwent several upgrades, including the installation of advanced instrumentation (i.e. wire-mesh sensors) built at the University of Michigan. These provides high resolution time-resolved measurements of the void-fraction distribution in the risers of the water-cooled RCCS facility. A phenomenological model has been developed to assess the water cooled RCCS system stability and determine the root cause behind the oscillatory behavior that occurs under normal two-phase operation. Testing under various perturbations to the water-cooled RCCS facility have resulted in changes in the stability of the integral system. In particular, the effects on stability of inlet orifices, water tank volume have and system pressure been investigated. MELCOR was used as a predictive tool when performing inlet orificing tests and was able to capture the Density Wave Oscillations (DWOs) that occurred upon reaching saturation in the risers. The experimental and numerical results have then been used to provide RCCS design recommendations. The experimental facility built at the University of Michigan was aimed at the investigation of mixing in the upper plenum of the air-cooled RCCS design. The facility has been equipped with state-of-the art high-resolution instrumentation to achieve so-called CFD grade experiments, that can be used for the validation of Computational Fluid Dynanmics (CFD) models, both RANS (Reynold-Averaged) and LES (Large Eddy Simulations). The effect of risers penetration in the upper plenum has been investigated as well.

AbstractAbstract
[en] In this lecture the advantages in using the electron cooling technique as complementary to stochastic cooling in the antiproton-proton machines at intermediate energy are analyzed. Electron cooling seems to be the right technique to be used for high precision particle spectroscopy. However this technique is quite limited at low and intermediate energies. (Auth.)

AbstractAbstract
[en] Possibilities to accumulate antiprotons in the Recycler are considered for three different cases: with current stochastic cooling, with upgraded stochastic cooling and with electron cooling. With stochastic cooling only, even upgraded, Recycler looks hardly useful. However, with electron cooling at its goal parameters and reasonably good vacuum in the Recycler, this machine would be efficient

AbstractAbstract
[en] In order to obtain a bunch of cooled antiprotons at rest in the laboratory, a bunch of particles (extracted from LEAR) is decelerated to very low energy and sent into a trap. After being trapped the bunch is cooled to very low temperature. In this contribution an explanation is given of what is meant by 'particles storing at rest in the laboratory'. Furthermore the trapping and cooling techniques are briefly discussed. (Auth.)

AbstractAbstract
[en] Thermoforming is one of the most versatile and economical processes available for polymer products, but cycle time and production cost must be continuously reduced in order to improve the competitive power of products. In this study, water spray cooling was simulated to apply to a cooling system instead of compressed air cooling in order to shorten the cycle time and reduce the cost of compressed air used in the cooling process. At first, cooling time using compressed air was predicted in order to check the state of mass production. In the following step, the ratio of removed energy by air cooling or water spray cooling among the total removed energy was found by using 1-D analysis code of the cooling system under the condition of checking the possibility of conversion from 2-D to 1-D problem. The analysis results using water spray cooling show that cycle time can be reduced because of high cooling efficiency of water spray, and cost of production caused by using compressed air can be reduced by decreasing the amount of the used compressed air. The 1-D analysis code can be widely used in the design of a thermoforming cooling system, and parameters of the thermoforming process can be modified based on the recommended data suitable for a cooling system of thermoforming

AbstractAbstract
[en] Mechanical filters are very important to ensure smooth operation of the secondary cooling system. The present condition of the mechanical filter treatment duration of PA-02 BT001 is increasing compared to other mechanical filters (PA-01 BT001 and PA-03 BT001). Seeing these conditions, it is very important to conduct an evaluation / study to find the cause and resolution through operating data starting in 2010 - 2017, collection of maintenance data starting from 2010 - 2017. After evaluation and review it can be concluded that the mechanical filter causes (PA-02 BT001) maintenance is most often compared to other mechanical filters, this is due to the location of the mechanical filter (PA-02 BT001) located on the side of the pipe straight at the far end so that dirt and lichen will be carried to the section. Besides this, PA-02 BT001 also serves cooling towers on the outside so that the growth of moss is more than the others. Based on these results, it is very important to review the mechanical filter operating schedule, maintenance scheme and the use of anti-moss in secondary cooling system water. (author)

AbstractAbstract
[en] In this lecture some beam cooling techniques are discussed, among which are: the stochastic cooling method, where one gets damping of particle oscillations by means of a feedback system; and the electron cooling technique by which damping is obtained in the interaction of the heavy-particle beam with an electron beam.
