Course objectives:
Introduction to processes of combustion and heat radiation, and methods for their calculations inside furnaces, boilers and combustion chambers. The objective is to provide the required foundation for students involved in research on any aspect of reacting flow, combustion and radiation, to be familiar with mathematical modelling and numerical simulations, which then can serve as guidance toward greater understanding of combustion and radiation processes that is required for producing combustion devices with ever higher efficiency and with lower pollutant emissions.
Student responsibilities:
Grading and evaluation of student work over the course of instruction and at a final exam:
Evaluation of the project assignments (40%), evaluation of the results achieved at the colloquia or exams (60%).
Methods of monitoring quality that ensure acquisition of exit competences:
Monitoring of the student attendance at the classes, interactive teaching process with active student participation in discussions during lectures and laboratory exercises. Project is used to assess the student"s ability for modelling and solving real practical problems related to combustion and radiation processes. Evaluation of the student presentation of the project. Evaluation of the results achieved at the colloquia and oral exams. Consultations. Student questionnaires.
Upon successful completion of the course, students will be able to (learning outcomes):
Upon successful completion of this course, the student will be able to: - analyze combustion and heat radiation processes in modern engineering systems; - perform a stoichiometric calculation of fuel combustion; - select the most appropriate model and numerical method for numerical simulation of different type of fuels (gas, liquid, solid fuels); - perform numerical simulation of gas fuel combustion; - perform numerical simulation of liquid fuel combustion; - perform numerical simulation of solid fuel combustion; - analyze and solve combustion and radiation problems in modern combustion chambers by using appropriate computer CFD packages; - critically evaluate and discuss specific engineering combustion and radiation problems, inculuding polutants; - present the results of numerical simulations of combustion and radiation processes.
