I Skimmed the article. There are a few major problems I can see with it. The first one is whether or not they use a flow solver that handles viscous effects (most flow solvers that I have seen can not). In fact most solvers that solve the viscus equations have to remove some other flow...

Dr. Dodge, In conventional turbines the cross sectional area of the fluid path increases as the working fluid is expanding to extract energy. The same is true of the Tesla. The exhaust ports need to be sized correctly for the specific volume of the working fluid in the expanded condition.

Linuxguy, I highly doubt there is any problem creating the turbine today. All the parts, materials and processes exist to make the unit. The problem I have run into is getting a machinist who is creative enough to make the parts. But if you really know how to model and draw the parts that is a...

Just wanted to post an update to let everyone know I'm still working on things. Right now I'm working on some programming for the data collection.

JoeEngineer, I'm not sure I follow exactly what you mean. I guess you are interested in plotting the streamlines. But really all that's needed is some way to know how long a particle is in the case. Putting rotating TCs and PTs on it is very tough at least on the design I have. But if that's...

RonL, Flow is a function of the difference in pressure between high and low... a vacuum can be considered zero pressure for all practical purpose and aids in extracting as much energy as possible. If my memory serves me Work is defined as the integral of P*dV... or simply the change in...

RonL, A thermodynamic converter in my opinion is anything that converts thermal energy into some other type of energy. A turbine with generator is a thermal to electrical converter however not a direct one (requires two steps). Additionally pulling a vacuum happens on any turbine system that...

Joe Engineer, What type of data do you want to see collected? I'm sure I have about 5 to 8 extra channels I can put to the task on my Data Acquisition system. I just have to write the C code for the conversions.

Joe Engineer, Sharing data is a great idea. However it appears very few people have even attempted to properly document the data they get. How would you go about collecting data?

I agree most sites out there are bogus. Most of the technical documents I've read are also bogus or seem to be. I just spent the past year working with actual steam turbines (not TT type). Impingement is a problem around condensation states. But just because there is no impingement (angles)...

Hi sorry for the extreme delay in posts. I changed e-mails and forgot the password for NateD as soon as the administrator gets back to me I'll switch back to that name... Until then NateD2 is the same person as NateD. I status update on my work. For the past year I have been in the process of...
