Heat Transfer and Fluid Flow Simulations (FSI-ITM)

Academic year 2021/2022
Supervisor: doc. Ing. Jaroslav Katolický, Ph.D.  
Supervising institute: EÚ all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:
The course objective is to provide student with principles of computational modelling of fluid flow and heat transfer, using both theoretical and practical approaches.
Learning outcomes and competences:
Students will acquire the theoretical basis of computational modelling of fluid flow and heat transfer (discretization methods, transient solution, convective-diffusion problems, algorithms). In the practical part they will experience work with CFD codes (set up of models, discretization of solution domain, boundary conditions, management of calculations, postprocessing.
Prerequisites:
Theoretical basis of heat transfer, thermomechanics and fluid mechanics.
Course contents:
The course consists of with theoretical and practical parts. The following topics are dealt with in the theoretical part: Fundamentals of numerical modelling. Heat conduction in one- and two-dimensional coordinate systems. Control-volume discretisation method. Source linearisation, boundary conditions, solution of algebraic equations systems (TDMA algorithm). Computation schemes for unsteady conduction. Equations of viscous laminar flow, general transport equation. Discretisation of convection-diffusion problems. Pressure-velocity field solution algorithm. The following topics are dealt with in the practical part: CFD-code Star-CD practice (steady 2-D flow with heat transfer, natural convection, unsteady problems).
Teaching methods and criteria:
The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.
Assesment methods and criteria linked to learning outcomes:
The graded course-unit credit awarding is based on the results of the semester project.
Controlled participation in lessons:
Attendance at seminars is required. Absence from seminars can be compensated by attending seminars with other group of students or for via a make-up project.
