    Galvanic Corrosion Prevention

    Hello! I have a case where a tight contact, to transfer heat, is needed between a part made from low carbon steel (with zinc chromate platting) and a part from aluminum or copper. The part made from steel is of cylindrical shape, 2” dia. The part made from aluminum is a ring fitted over the...

    Aluminum to Steel Connection

    CoryPad, Thank you for the assistance. However, how to relate your first answer with the Anodic Index rule of 0.15V or less for the galvanic corrosion to do not occur? Again, low allow steel - 0.85, aluminum - 0.90. What coating is suitable for the marine environment? Thank you, again.

    Aluminum to Steel Connection

    Would galvanic corrosion occur between zinc-chromate coated steel and aluminum alloys of 5000 or 6000 series? The environment is harsh – sea humidity. I read, on the Internet, that if difference between Anodic Index numbers is more than 0.15 V, than the galvanic corrosion does occur...

    Thermal CFD Analysis Software Perfomance

    You brought an important factor(s) that I assumed (rightly or wrongly) Flotherm is capable of doing - to mesh according to size of an object and to use tetrahedral elements. I did see that the software, after a CAD model is brought in, goes through geometrical simplification of the model, i.e...

    Thermal CFD Analysis Software Perfomance

    Bgoldstein, Thank you for the detailed answer. Few days ago, I had a one hour web demo by the Flomerics. Yes, I did observe a rectangular grid, density of which could be controlled. What do you mean by "non-conformal" grid? ZP
