This study for the first time produced the PVA hydrogels with immobilized cells by two-stage crosslinking which have high shape stability at dry-rewet cycles and, when recovered after sequentially three 24-hr cultivations, reveal high bioactivity in wastewater treatment. The [B(OH)(3)][SO42-...
(2019). The produced hydrogels maintained high bioactivity and shape stability under repeated dry-rewet cycles. Also, this study for the first time examined the feasibility of using PVA-Sb-sludge hydrogels for wastewater treatment. The chemical oxygen demand (COD) was used as the nutrient removal...
Dryout and rewet of the groove are allowed; the front location is determined numerically using conservation of mass and linear extrapolation. Several numerical test results are presented and discussed.关键词: BOUNDARY CONDITIONS CAPILLARY FLOW CONSERVATION LAWS EVAPORATION FLUID FLOW GRAVITATIONAL EFFECTS ...
3D Propagation of CHF/Rewet Front within Rod Bundle in Turbine-Trip-w/o-Bypass Simulation: Experimental and Numerical Investigation based on Porous Media Investigation based on experimental and numerical simulation of three-dimensional transient propagation of a dry-out front within a nuclear fuel rod...
Eventually, according to the TRACE/PARCS calculations, during the dryout phase, the temperature ratchets above the minimum stable film boiling temperature (Tmin). Once the temperature exceeds Tmin the fuel surface becomes locked into a film boiling heat transfer regime, i.e. it fails to rewet,...

Heat flux induced dryout of thin liquid films on an inclined copper plate was studied. Rewet of the dried out area is also considered. The four fluids used to form the thin films exhibited very different dryout and rewet characteristics. The contact angle and hysteresis effects were found to...
