This case study presents the benchmark validation of CFD simulation results of the Potsdam Propeller Test Case (PPTC) using CFD Support’s TCFD flow solver with a Pointwise mesh. PPTC is a marine propulsor that was extensively measured by SVA Potsdam. The aim of this benchmark was to evaluate the combined use of TCFD with Pointwise […]
The experiment for viscosity for the Fluid Mechanics Laboratory. Material to go with this video is as follows:
- Variation in Viscosity (instructor’s handout)
- Material on the viscometer used:
- BROOKFIELD DVE Digital Viscometer Operating Instructions Manual No. M15-356-B0916
- More Solutions to Sticky Problems. A very useful guide to the application of the viscometer, which may be very helpful in running the experiments and putting together the reports.
- Taking the Last Voyage with Newton and Pascal: The Life of
Saint-Venant. His name is better known in mechanics of materials, but Saint-Venant was the first researcher (even before Stokes) to include viscosity in fluids on a theoretical basis. This will be important when we get to the wind tunnel test.
Fourth in the series of Fluid Mechanics Laboratory videos.
More information on the subject:
- Buoyancy and Stability: An Introduction (instructor’s handout)
- The Experimental Determination of the Metastatic Height. A textbook treatment (with worked example) of the experiment actually run.
- Know Your Own Ship
- Naval Ships’ Technical Manual Chapter 096: Weights and Stability
- The Propulsive Power of Screw Ships. Once you get them stable, ships have to go somewhere, and this is an investigation of how much power they take to do it.
- When the Pathfinder Gets Lost: some students like to “follow the lead” of someone else to get the course work done. That can have negative results other than those described in the syllabus, just like this example.
