Objectives and Contextualisation
The main objective is twofold, on the one hand the application with criteria of tools for modelling, simulation and optimisation of chemical, biotechnological and environmental processes and, on the other hand, to work on the bases of Computational Fluid Dynamics.
The specific objectives of the course are:
- Formulate mathematical models for different processes from non-stationary state balances and other additional equations.
- Numerically solve mathematical models with simulation programs and analyze the results.
- Use methods for univariate and multivariate mathematical optimization.
- Adjust mathematical models. Analyze the sensitivity of model parameters.
- Apply the basic notions of experimental design.
- Develop calculation programs, based on the fundamental principles of Transport Phenomena and the appropriate Numerical Methods.
- To solve problems of Transport Phenomena in such a way that the student can understand how they are structured and which are the principles of operation of the commercial CFD packages, mainly ANSYS

Content
The subject is structured in two modules:
Modeling and optimization of processes
- Modelling of chemical, biological and environmental processes
- Simulation of processes with ordinary differential equations
- Simulation of processes with differential equations with contour conditions
- Simulation of processes with differential equations with partial derivatives
- Univariate, multivariate and constrained optimization methods
- Model fit: Parameter Determination and Sensitivity Analysis

Computational Fluid Dynamics
- Introduction
- Geometry and mesh
- The integrator
- The Visualizer
- Case Studies
Methodology
The course will be developed in theory classes and theoretical-practical classes. In addition, during the course different proposed cases will have to be solved and presented, which will be carried out mainly outside the class schedule.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment
Evaluation
(a) Scheduled evaluation process and activities
The course is divided into two independent modules: 1) Computational Fluid Dynamics (CFD) and 2) Process Modeling and Optimization (MOP).
Below are the evaluation activities of each module of the subject with its percentage of weight on the final grade:
Process Modeling and Optimization
- Activity 1 (15%). Problems
- Activity 2 (60%). Partial exam
- Activity 3 (25%). Modelling work on real scientific papers.
Computational Fluid Dynamics
- Activity 1 (5%). Course work CFD1.
- Activity 2 (10%). Course work CFD2.
- Activity 3 (15%). Course work CFD3.
- Activity 4 (70%). Exam.
The final grade is the average grade of the two modules. The grade for each module must be greater than or equal to 4.5/10 in order to make the average.You need at least a 3.0/10 in each of the exams to pass the module.
The non-presence in class when evaluation tests are carried out is a zero of the activity, without possibility of recovery.
b) Programming of evaluation activities
The schedule of evaluation activities will be given on the first day of the course and will be made public through the Moodle.
c) Recovery process
Student can apply for make-up of each module as long as they have presented himself to a set of activities that represent at least two thirds of the total grade of the module. Of these, those students who have a grade of more than 3.0 on average for all the activities in the module may be presented for make-up.
The make-up process of each module will consist of an exam with all the contents of the module. The maximum grade that can be obtained using this procedure will be 6.0 in each module recovered.
d) Procedure for revision of qualifications
For each assessment activity, a place, date and time of review will be indicated where the student can review the activitywith the professor. In this context, complaints can be made about thegrade of the activity, which will be evaluated by the professor responsible for the subject. If the student does not submit to this review, this activity will not be reviewed at a later date.
e) Qualifications
In case one of the modules does not reach 4.5/10, the maximum final grade of the course will be 4/10 and the suspended module will have to be repeated the following year.
Honour plates. It is the decision of the faculty responsible for the subject to award an honorary matriculation grade. UAB regulations state that MH can only be awarded to students who have obtained a final grade equal to or higher than 9.00. Up to 5% of the total number of students enrolled may be awarded.
A student will be considered non-assessable (NE) if he/she has not presented to a set of activities whose weight equals a minimum of two thirds of the total grade of the subject.
f) Student Irregularities, Copying and Plagiarism
Without prejudice to other disciplinary measures that may be deemed appropriate, irregularities committed by the student that may lead to a variation in the grade of an evaluation act shall be graded with a zero. Therefore, copying, plagiarism, cheating, letting copy, etc. in any of the evaluation activities will involve suspending it with a zero. Evaluation activities graded in this way and by this procedure will not be recoverable.
h) Evaluation of Repeating Students
The only change in subject evaluation for repeaters is the possibility of maintaining grades from a module passed the previous course. This option must be communicated by email to the teacher responsible, no later than 15 days after the start of classes.
