June 1st. 1915. Re Steam Separator Radiator. The phenomenon that you have discovered with reference to our standard engine is of considerable interest, and shows that the fault of the loss of water is very largely a question that must be dealt with in the engine rather than in the radiator. It probably occurs in all engines more or less, but does not occur until the water actually boils in the engine jackets. It would be interesting to find out if a similar action happened in the aero engine. That is, supposing that you are circulating from a tank, does the level rise materially when the water boils ? if it does, it shows an accumulation of steam somewhere in the jacket, which might be the cause of considerable trouble. We noticed this phenomenon in connection with the Sheffield-Simplex, but thought it was largely due to the want of slow circulation of the water. In this case the water boiled and formed steam pockets in the engine long before the water in the radiator was boiling. In our case it appears that the water circulation is sufficiently rapid that the whole of the water is on the point of boiling | ||
