Surrogate fuel possesses physical and chemical properties identical to the real fuel, however, it contains significantly fewer components, enabling practical application. In this project, the composition of the surrogate mixture is optimized according to measured and calculated material properties of the investigated fuel sample regarding the original composition. The objective is to determine a surrogate mixture composed of a few components but following the thermophysical properties of the real fuel sample to model atomization, evaporation, and heat release related phenomena.<\/p><p style=\"text-align: justify;\">Reference:<br \/>Huang Z, Xia J, Ju D, Lu X, Han D, Qiao X, et al.

Numerical solution methods are burdened by a number of errors, e.g., such a typical error is\nthe dissipation (artificial damping) error. This error is already present when simulating reversible and non-dissipative systems, thus in case of the simulation of an irreversible and dissipative system the physical and numerical damping are indistinguishable.\nWithin the framework of the task, the examination of a vibratory system with several (but finite) degrees of freedom must be performed by several traditional and symplectic numerical methods.<br \/>A feladat keretein bel\u00fcl egy t\u00f6bb (de v\u00e9ges) szabads\u00e1gi fok\u00fa rezg\u0151rendszer vizsg\u00e1lat\u00e1t kell\u00a0 elv\u00e9gezni sz\u00e1mos hagyom\u00e1nyos \u00e9s szimplektikus numerikus m\u00f3dszer seg\u00edts\u00e9g\u00e9vel.

The literature describes this phenomenon as \u201cPiston\u201d-effect, which is mentioned by many works as the fourth mode of heat propagation, although the phenomenon is merely a result of thermal-mechanical coupling. This phenomenon is measured on sulfur hexafluoride in space with microgravity conditions, however, velocity field was assumed to be zero in the evaluation, as a consequence, the pressure field is homogeneous, thus the model does not take pressure waves into account.

The variability of renewable production is still mostly balanced by fossil fuel power plants, but role of energy storage systems is expected to increase in the near future. Energy storage can be used for balancing the errors of power forecasts and thereby reduce the imbalance penalties, for shifting the renewable production to the peak load times even on a daily or seasonal timescale, and for other innovative means that support the operation of the grid. The evaluation of the topic can focus on either deeper modeling of a single storage technology, or on the cooperation of multiple storage systems to fulfill a complex storage goal.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-97cf4e9 elementor-widget elementor-widget-text-editor\" data-id=\"97cf4e9\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<h4 style=\"text-align: center;\"><span data-sheets-formula-bar-text-style=\"font-size:13px;color:#000000;font-weight:normal;text-decoration:none;font-family:'Arial';font-style:normal;text-decoration-skip-ink:none;\">Analysis of the optimal energy mix of the future<\/span><br \/>Supervisor:\u00a0 <a href=\"http:\/\/www.energia.bme.hu\/munkatarsak\/mayermj\/\" target=\"_blank\" rel=\"noopener\"><span data-sheets-value=\"{\" data-sheets-userformat=\"{\">Mayer Martin J\u00e1nos<br \/><\/span><\/a><\/h4><p style=\"text-align: justify;\">Increasing the share of renewable energy sources is the main element of most energy strategies created today. However, the optimal future energy mix can only be simulated based on the hourly time-series data of the expected load and generation profiles. Such simulation can not only aim to find the optimal share of different energy sources, but also the optimal design parameters of the power plants, e.g. the tilt angle of photovoltaic systems. The results can serve as a basis for recommendations on the newly installed power plants, and they can also reveal the time periods in the future when renewable energy surplus can be expected, which is important information for sizing storage systems and estimating the environmental impacts of electricity production.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4973da7 elementor-widget elementor-widget-text-editor\" data-id=\"4973da7\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<h4 style=\"text-align: center;\"><span data-sheets-formula-bar-text-style=\"font-size:13px;color:#000000;font-weight:normal;text-decoration:none;font-family:'Arial';font-style:normal;text-decoration-skip-ink:none;\">Ammonia as an internal combustion engine fuel<\/span><br \/>Supervisor:\u00a0 <a href=\"http:\/\/www.energia.bme.hu\/munkatarsak\/bereczkya\/\" target=\"_blank\" rel=\"noopener\"><span data-sheets-value=\"{\" data-sheets-userformat=\"{\">Bereczky \u00c1kos<\/span><\/a><\/h4><div>- Review of ammonia production technologies with special regard to CO2 emissions<br \/>- Overview of ammonia use options<br \/>- Development of a measurement system and measurement plan for the tests<br \/>- Summary of results<\/div><div>\u00a0<\/div><div>Reference:<\/div><p><a href=\"https:\/\/doi.org\/10.1016\/j.ijhydene.2019.12.209\">https:\/\/doi.org\/10.1016\/j.ijhydene.2019.12.209<\/a><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-f7ccf7d elementor-widget elementor-widget-text-editor\" data-id=\"f7ccf7d\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<h4 style=\"text-align: center;\"><span data-sheets-formula-bar-text-style=\"font-size:13px;color:#000000;font-weight:normal;text-decoration:none;font-family:'Arial';font-style:normal;text-decoration-skip-ink:none;\">Hydrogen technology in the waterborne transport sector<\/span><br \/>Supervisor:\u00a0 <a href=\"http:\/\/www.energia.bme.hu\/munkatarsak\/bereczkya\/\" target=\"_blank\" rel=\"noopener\"><span data-sheets-value=\"{\" data-sheets-userformat=\"{\">Bereczky \u00c1kos<\/span><\/a><\/h4><div><span data-sheets-formula-bar-text-style=\"font-size:13px;color:#000000;font-weight:normal;text-decoration:none;font-family:'Arial';font-style:normal;text-decoration-skip-ink:none;\">1.\/ Introduction to hydrogen technology in general;
