简介：
Due to the continuous increase in the performance of central processors and other components of electronic components, heat generation from such elements is also noticeably increasing. If the excess temperature is not removed from the surface of the energy-generating elements in a timely manner, clock failures will be observed and, as a result, the efficiency of electronic devices will significantly decrease, up to complete failure. In order to eliminate such negative effects, it is necessary to maintain comfortable temperature conditions. In this regard, researchers and large manufacturers of electronic equipment are developing cooling systems and ways to increase the intensity of heat removal from heating elements. Within the framework of this project, multiparametric studies of the currently most common active cooling system will be carried out, where the flow of a gas or liquid medium is considered as a refrigerant. Methods of intensification will be considered due to the peculiarities of the geometry of the channel or heating element, the rib and porous structure of heat-removing inserts, the use of various refrigerants and taking into account the influence of magnetic fields on heat and mass transfer processes. $A whole series of studies on active cooling systems is planned, namely:$-Numerical simulation of laminar mixed convection regimes in a spatial channel with a constant volumetric heat release source, taking into account the determining factors of heat and mass transfer processes (geometric and thermophysical characteristics of the heating element);$-Modeling of heat dissipation systems located on the surface of the heating element, using radiators made of materials with different thermophysical properties, using solid and porous fins;$-Detailed numerical modeling of heat generating elements and their active cooling - will take into account zones of active heat release, periodic modes of energy-generating sources (processor and chip clock frequencies), zones of contacts of various kinds of materials, setting appropriate boundary conditions for complex tasks of conjugate mixed convective heat exchange;$-numerical simulation of the processes of mixed convective heat transfer in channels under the influence of magnetic fields of various strengths and orientations, assessment of the influence of these parameters on the intensity of heat transfer and the hydrodynamics of the cooling medium;$-Own computational codes will be developed based on the methods of finite differences and the lattice Boltzmann method;$-An algorithm for parallel GPU computations of mixed convective heat exchange in channels based on the lattice Boltzmann method will be implemented.$To implement the tasks set, it is planned to involve a student (Sh. Xu, Master of 1 year of study in mechanics and mathematical modeling) and phd student (E. Shulepova, graduate student of 3 years of study in the scientific specialty 1.1.9 - mechanics of liquid, gas and plasma)
