abstract: in this study, al 2 o 3 /eg and tio 2 /eg nanofluids as coolants have been used in the double-tube heat exchanger. the hot solvent inlet heat exchanger must be cooled down with a specified amount. we can use nanofluids as coolants in the heat exchanger for optimization of the heat transfer area. therefore, the efficacy of nanofluids as coolants is verified. furthermore, flow rate of c...

Three Gram-positive, rod-shaped, oxidase-negative, non-spore-forming, non-motile bacteria (KSS-3Se(T), KSS-4Se and KSS-10Se) were isolated from a coolant lubricant. 16S rRNA gene sequence analyses revealed almost identical sequences, with only a few (<10 positions) differences for these three isolates. Comparisons showed the highest similarities to Corynebacterium pilosum NCTC 11862(T) (97.6 % ...

Increasing the power and reliability of microelectronic components requires heat sinks with greater transport performance. This study investigates hydraulic performance a silicon sink under constant flux 100 W/cm2 liquid coolant running through parallel microchannels. The coupled transfer walls coolant, modelled as single-phase fluid, is examined over Reynolds number range 100?Re?350 for micro-...

The initial design life of nuclear power plant is 40 years. In 60 year extending license application, the fatigue component should be evaluated under influence factors pressurized water reactor coolant environment. Because original used a more conservative analysis method, result could not meet requirement Cumulative usage factor RCC-M. An optimizing method studied, and as an example Safety Inj...

The neutronic performance of small size critical dedicated burners is investigated here according to the type of recycling performed (MA supply alone or together with some fissile element), the nature of the possible fissile supply (Pu, enriched U, U bred from Th), the coolant type (sodium or lead). The main neutronic parameters are given, such as reactivity coefficients, together with mass bal...

Neutronics analysis has been performed for LIBRA-LiTE. Using liquid lithium as a coolant and breeder results in more attractive neutronics performance features compared to Li17Pb83. The final focusing magnets and the front rows of the INPORT tubes have to be replaced every 1 and 3 years, respectively. The steel chamber wall, roof, and bottom plates are lifetime components. The overall reactor t...
