designing drilling fluids for drilling in deep gas reservoirs and geothermal wells is a majorchallenge. cooling drilling fluids and preparing stable mud with high thermal conductivity are ofgreat concern. drilling nanofluids, i.e. a low fraction of carbon nanotube (cnt) well dispersed inmud, may enhance the mixture thermal conductivity compared to the base fluids. thus, they arepotentially usef...

In micro-fluid systems, fluids are injected into extremely narrow polymer channels in small amounts such as micro-, nano-, or pico-liter scales. These channels themselves are embedded on tiny chips. Various specialized structures in the chips including pumps, valves, and channels allow the chips to accept different types of fluids to be entered the channel and along with flowing through the cha...

This article presents an experimental investigation on effects of morphology of nanoparticles on the viscosity nanofluids (NFs). Water and ethylene glycol were used as base fluids. A two step method was used for preparation of NFs. SiO2 nanoparticles, CNT and graphene nano sheets were dispersed in the base fluids separately with the volume fraction ranging from 0.05% to 1.5%. Stability of the n...

In recent decades, the use of nanofluids has attracted much attention due to its application in various fields such as medical and industries like oil and gas. The combination of nanoparticles with base fluids and its type can produce different results depending on the characteristics of the nanoparticles, one of which is the effect of changes in the viscosity and thermal conductivity of the na...

Nano-clean fracturing fluids have broad application potential in coalbed methane reservoir owing to their high stability, good temperature resistance, low filtration loss, and strong frictional resistance reduction. However, the sand-carrying regularity of nano-clean reservoirs is unclear, especially for complex fractures with variable directions. This study established a sand transport model t...

In this experimental based research work, the performance of Thermal Energy Storage System (TESS) during charging (melting) and discharging (solidification) processes were studied under varying conditions. The results from the CFD simulations for these conditions were published earlier. Here, the experimental results had been discussed. Paraffin wax concentration was varied to form the TESS. Al...

The viscosity of polydispersed graphene nanosheet (5 nm–1.5 lm) suspensions (GNS) and its behavior with temperature and concentration have been experimentally determined. A physical mechanism for the enhanced viscosity over the base fluids has been proposed for the polydispersed GNSs. Experimental data reveal that enhancement of viscosity for GNSs lies in between those of carbon nanotube suspen...

Nano-aerosols composed of large agglomerates (LA) (>100nm) are more likely to promote pulmonary clearance via macrophages phagocytosis. Small agglomerates (SA) (<100nm) seem to escape this first defense mechanism and are more likely to interact directly with biological material. These different mechanisms can influence pulmonary toxicity. This hypothesis was evaluated by comparing the relative ...
