 Lecturers in charge: prof. dr. sc. Neven Duićprof. dr. sc. Hrvoje Jasakdoc. dr. sc. Milan Vujanović Lecturers: Tessa Uroić mag. ing. mech. ( Exercises ) doc. dr. sc. Milan Vujanović ( Exercises ) Course description: Course objectives: Introduction to the numerical methods used in continuum mechanics, with an emphasis on numerical modelling of heat and mass transfer. The main objective of the course is to provide knowledge necessary for the mathematical modelling of heat and mass transfer and numerical simulations, which then can serve for a better understanding of real processes in modern engineering systems.Enrolment requirements and required entry competences for the course: Thermodynamics I, Fluid Dynamics IStudent responsibilities: Regular attendance at the classes (the lectures and computer exercises). Independent solving and successful submission of the project tasks assigned during the classes.Grading and evaluation of student work over the course of instruction and at a final exam: Ocjenjivanje programskih zadataka (45%), ocjenjivanje uspjeha postignutog na usmenom ispita (55%).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 engieering problems. Evaluation of the student presentation of the project. Evaluation of the results achieved at oral exam. Consultations. Student questionnaires.Upon successful completion of the course, students will be able to (learning outcomes): apply conservation laws; apply Finite Volume Method to the fluid flow analysis; generate a mesh for Finite Volume Method; select the difference scheme and numerical algorithm for pressurevelocity coupling; select the boundary conditions and turbulence model; analyze and solve mass and heat transfer problems in modern engineering systems; perform Finite Volume Method analysis by using appropriate computer CFD packages; present the results of numerical simulations of mass and heat transfer.Lectures 1.
