Abstract— In connection with the heated political situation to the east of the European Union (EU) borders, there is a growing interest in the discovery of new reserves of natural gas or new suppliers of this fossil fuel. The following article discusses the current suppliers of natural gas to the EU, the energy self-sufficiency of the EU and the possibility of transporting natural gas in the form of LNG.
2. Design of an Experimental Device for the Analysis of the Influence of Sound Waves on the CPU Cooling Process - Part II
Abstract— The article describes the calibration procedures and the creation of a series of initial data packages as a basis for comparative experiments in the process of increasing the efficiency of CPU air cooling in the case of commonly available types of coolers. It then describes the course of the experiment, the input parameters and the data obtained from the calibration of the basic model at different power settings of the fan mounted on the DeepCool AG200 air cooler. The output of the article is a model of cooling performance based on fan speeds and ambient operating temperature.
3. Structural Design of Atypical Metal hydride Tank and Investigation of Generated Temperature Fields: Part II
Authors: Filip Duda, Natália Jasminská, Peter Milenovský
Abstract— In part 1 of the article, temperature fields generated in a metal hydride tank of an atypical shape were investigated, where the tank was immersed in a cooling liquid. For the total temperature in the storage tank to be reduced even more, it is necessary to design an effective passive heat exchanger system that will remove this generated heat towards the inner wall of the storage tank, where this heat will then be effectively removed by the cooling liquid located on the outside of the storage tank. In part 2 of this article, an internal heat transfer intensifier is designed and subsequent verification of temperature fields using simulation in the ANSYS CFX program.
4. Design of a Model of Liquid Feeder to an Incinerator of Hazardous Waste and its Optimization from the Cooling Point of View: Part II
Authors: Ivan Mihálik, Marián Lázár, Tomáš Brestovič, Peter Milenovský
Abstract— A series of articles aimed at the cooling of the liquid radioactive waste feeder into the incinerator space optimization. The second part examines ion-exchange resins used in the nuclear industry and the possibilities of their combustion. A 3D model of a radioactive waste feeder with different variants of cooling pipes is proposed. Using numerical simulation, the cooling efficiency of individual variants is compared.
5. Liquid Impact Sheet Metal Deformation of Superni (Inconel) 718 using Inclined Edge (Conical) DIE
Authors: E. Hazya, Dr S Gajanana, Dr. P. Laxminarayana
Abstract— Liquid/Hydraulic impact forming is a sheet metal forming process in which a dead weight drop freely from a certain height over a piston working inside a cylinder containing liquid or hydraulic fluid, generates shock waves which reach the sheet metal kept at a lower part of the cylinder and deforms it to the shape of the die placed below the sheet metal. In the present work Taguchi design of experiments (DoE) technique is used in order to find the effect of input parameters on impact force for deformation of superni (Inconel) 718 using inclined edge die. Contribution of each factor on output is determined by ANOVA (Analysis of Variance) and also an attempt is made towards green manufacturing by adopting used gear and vegetable oils as operating fluids. The outcome of this research will be very much useful for medium and small segment industries in getting the pre-form of the product with least cost.
6. Use of Peltier Cells in the Cooling Process
Authors: Romana Dobáková, Lukáš Tóth, Tomáš Brestovič
Abstract— Peltier cells represent an interesting alternative to conventional cooling methods and are currently being used in areas where conventional cooling methods are not suitable. They can produce heat and cold when supplied with electricity. The article discusses the possibilities of using Peltier cell technology in the cooling processes of electronic components in an environment where it is not possible to use conventional cooling methods due to their size or the inappropriateness of the given type of cooling. It compares cooling options and describes basic power calculation procedures to cover cooling power needs. Thermoelectric cooling has several advantages, including the absence of a cooling medium, the possibility of precise temperature regulation, small dimensions and a relatively long service life.
