Issued topics of Doctoral Study Program

  1. Development of algorithms for solving heat and mass transfer with phase and structural changes using GPU

    The theme is aimed at the development of numerical algorithms designed primarily for solving heat transfer with phase transformations using high parallelization of code. For the solution should fully take advantage of special graphic processor units TESLA. Expected to use MATLAB and C++. Algorithms can be network-oriented methods (eg method of control volumes) or mesh free methods.

  4. New technologies for the controlled heat storage

    The aim is the development and validation of technologies for controlled accumulation of energy storage especially in phase change materials or a combination of multiple technologies.

  5. Research of internal flow and spraying process of advanced designs of Spill-return pressure-swirl atomizers

    Motivation and Goals Spill-return pressure-swirl atomizers (SR PSAs) are wrongly forgotten devices suitable for spraying liquids under specific, nowadays emerging cases when a wide range of turn-down ratios, low pressures, high liquid viscosities or very low flowrates are required. They are not as studied as simplex atomizers namely in the application relevant conditions (elevated pressure, temperature, cross- or coo-flow). The quantification and characterization of the geometrical and kinematic (the displacement speed) characteristics of the gas-liquid interface during the spraying process remain an important challenge in the exploration of the internal flow, discharge and sheet formation, and primary/secondary atomization phenomena. The continuing advances in optical diagnostic methods as well as in CFD (computational fluid dynamics) simulations allow advancing our knowledge to a new level. The experiments performed under specific conditions require a modification of the present experimental infrastructure and improvement of the setup of optical diagnostic approaches along with development and validation of new methodologies for the data analysis and procedures to characterise the liquid-gas flows. The PhD study aims to elucidate the processes related to SR PSAs for application in combustion turbines (the internal flow and air core dynamics, spray stability and cone angle) and to explain the effect of realistic conditions on the spray development. The applicant will focus on several hypotheses, where no available data can be found, are insufficient, or contradictory conclusions were made by different authors: - The internal arrangement (spill-line configuration and shape of convergent part of the swirl chamber) affects the internal flow and formation of the liquid sheet outside the atomizer. - The presence of the external cross/coo-flow induces turbulence and affects the primary breakup distance of the liquid sheet and resulting spray quality. Approaches and methods The applicant will benefit from existing knowhow and methods developed in the Spray laboratory. The gas-liquid flow and interfaces will be tracked using a high-speed camera, image-based object sizing techniques and PIV algorithm. The flow field inside the atomizer and on the liquid film will be estimated by means of particle tracking, applying several assumptions and simplifications. Combination of the particle position/velocity measurement and the model assumptions allows to fully describe the particle kinematics and by tracking multiple particles to estimate the internal flow and to describe the entire flow field. Doppler-based methods will give direct quantitative data on the velocity and size of particles. The advanced experiments supported with CFD simulations and analytical approaches will be used to find out the properties of the internal flow and spray and allow a better understanding of the coupling between interface velocity and geometry. Note: The experimental equipment is available at the Department of Thermomechanics and Environmental engineering, EU FSI. The student will provide the PhD study in the frame of the research projects of specific research, basic research projects of the Czech science foundation, etc.
