MAS103 3D-Modelling and CFD

Contents and structure

The course will teach students about preparing 3D CAD models for CFD simulation purposes. Students shall learn to develop models in PTC Creo and Ansys Workbench Computational. One will learn about Fluid Dynamics (CFD) is a numerical method to solve problems in fluid and heat flow. It will also be possible for the simulation of the energy transfer and simulation of the interaction between the solids and fluids (Fluid Solid Interaction simulation).

 

Preparing CAD model in Creo package, preparing the necessary simplifications, correct geometry in a way to prepare proper simulation grid.

Preparing correct geometry simulating wind or water turbine. Defining flow domain and solid domain.

Preparing appropriate grid for CFD simulation, define boundary conditions, turbulence models, walls defining, etc.

Learning Outcome

Upon completing the course, students will have the following learning outcomes:

 

Proficiency

• Knowledge of how to prepare CAD models for CFD modeling.
• Knowledge of basic assumptions and general requirements to improve geometry for CFD applications.
• Knowledge of CFD modeling opportunity for energy transfer.
• Have knowledge of basic 2D drafting rules, manufacturing symbols, cut and relevant standards.

 

Skills

• Students are able to prepare the geometry of the CFD simulations with appropriate simplifications and requirements.
• Students are able to prepare the corresponding, simplified models (2D instead of 3D, using symmetry conditions, etc.), Replaces assemblies with a solid portions.
• Students are able to identify problems that can be simulated by CFD methods.
• Students are able to prepare CFD simulations with the appropriate boundary conditions, models of turbulence, fluid.
• Students are able to draw from CFD simulation results conclusions Press, speed and thermal distributions, mass and heat fluxes, forces on walls or solid bodies.

 

 

General competence

• Practice with project working.

Entry requirements

Mathematics and physics for engineers and knowledge of material science and fluid mechanics.

Teaching methods

Lectures, demonstration, exercises and written assignments.

Compulsory learning activities

A learning portfolio that consists of the following coursework:

• Five assignments part 1
• One written examination part 1
• Five assignments part 2
• One written examination part 2

Two of the elements from the learning portfolio, will be used in the portfolio assessment.

Four out of five of the written assignments must be passed before one is allowed to take the written examination part 1. After the written examination part one, another four out of the five assignments must be passed before one is allowed to take the written examination part 2. In case of absence that is not legitimate (sick leave) for examination part 1, one can not take examination part 2. For students who have legitimate absences (sick leave), there will be a new trial in the current semester.

Assessment

Portfolio assessment.

The portfolio assessment consists of the following coursework from the learning portfolio:

• One written examination part 1
• One written examination part 2

Each examination part counts for 50%. For students who have legitimate absences (sick leave), there will be a new trial in the current semester.

After an overall assessment of the elements in the portfolio assessment, a final grade is given for the course. Grading scale is A-F where F is fail. Detailed guidelines and deadlines are announced at the start of the semester.

Examination support material

Calculator, tecknical manual.
