Date I took this class: Fall 2008
Teacher: Dan Noren
Teacher's site: None listed
Grade earned: A
Book used: Thermodynamics an Engineering Approach
ISBN: 0-07-330537-5
Professor Noren is, overall, a very good teacher.
Noren gets side tracked easily but these detractions usually lead to interesting thermodynamics information.
Noren leads the class very gradually, clarifying every detail along the way.
Noren is a practical teacher. He teaches the course using specified guidelines and procedures which are easy to understand and apply to thermodynamic problems.
Noren assigns homework which he creates himself. All those who do the homework usually pass easily with A's.
Noren's exams are based exactly on the homework.
The Thermodynamics text is required but is not used in class. The only part of the book that is required are the data tables in the back which can be purchased separately.
Professor Noren gave 10 home work assignments throughout the semester.
This section, and the following sections, are dedicated to helping those interested in modeling thermodynamic equipment and cycles in Simulink.
All that is needed to begin are Professor Noren's
files, MATLAB software (Simulink included), and something to model.
Warning: Noren's files will not work in the newer version of MATLAB, only version 7.0.1 or older will work. This problem is currently being researched and a solution should come soon. For those students attending CSU, Sacramento there is a way to get access to an older version of MATLAB. See the
Instructions on how to access an older version of MATLAB. Please only use the remote servers for an hour or two a day! Strictly speaking the remote server should only be used by graduate students but undergrads can use it for short periods of time. I recommend building your model in the newer version and simply running it in on the remote server.
