Hydromechanics Calculation for Micro Sphere UO₂ Fuel Producted by Sol-Gelation Method

Relation between the jet steam velocity in nozzle and height of glue solution level and rela-tion between the jet steam velocity in nozzle and the pressure of glue solution level in pressure kettle are es-tablished with Bernoulli equation. The result calculated from this relations shows that the flow of gelation solution is of laminar, the effect of the height of solution level on the the jet steam velocity in nozzle is little and the maximum error for diameter of micro global UO₂, resulting from the height of solution level, is far more less than the control error.
