Course detail

Multiphysical Simmulation in Automotive Industry

FSI-QMO Acad. year: 2022/2023 Winter semester

The course will provide an overview of contemporary computational simulations used in the development of modern vehicles. Within the course, selected physical processes including a basic mathematical description are repeated. Preference is given to practical knowledge including lubrication and computational fluid dynamics (CFD). Emphasis is placed on the practical use of simulations within commercial software. Computational simulations are applied to typical tasks occurring in the automotive industry, such as hydrodynamic bearings, vehicle aerodynamics or rotor-fluid interactions.

Learning outcomes of the course unit

The student will acquire the skills of practical application of modern methods supported by knowledge of the necessary theoretical principles. The student will apply these skills in the development of motor vehicles in areas such as vehicle aerodynamics or powertrain cooling and lubrication.

Prerequisites

Knowledge of mathematics taught at the bachelor’s degree level and necessarily includes linear algebra (matrices, determinants, systems of linear equations), differential and integral calculus and ordinary differential equations.

Knowledge of basic hydrodynamics and thermodynamics.

Planned learning activities and teaching methods

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 course-unit credit is conditioned by active participation in the seminars, proper preparation of the semester work and fulfilment of the conditions of the control tests. The exam verifies the knowledge gained during lectures and seminars and is divided into a written theoretical part, part of the computational solution of lubrication, fluid flow and heat transfer and oral part. The exam considers the work of the student in the exercise. The student must score more than one half of points for the successful completion of the test.

Aims

The objective of the course is to provide basic knowledge in the problems of multiphysics simulations using computational fluid dynamics (CFD), which are applied in the development of motor vehicles and powertrains. The objective is also to obtain knowledge applicable in practice in the areas of lubrication of hydrodynamic and rolling bearings, piston and turbocharger seals and other structural components.

Specification of controlled education, way of implementation and compensation for absences

Exercises are compulsory, the form of replacing the missed lessons is solved individually with the lecturer or with the course guarantor. Lectures are optional.
