Keywords: Nanotechnology Flow boiling Heat transfer enhancement Multi walled carbon nanotubes (MWCNT) Chemical vapor deposition Multi phase flows a b s t r a c t In this study we measure the flow boiling heat flux on a horizontal heater that is heated from below. The horizontal heater consists of either a bare silicon wafer or a silicon wafer that is coated(More)
Nanotechnology is a new and emerging technology with wealth of applications. It involves the synthesis and application of materials having one of the dimensions in the range of 1–100 nm. A wide variety of physico–chemical approaches are being used these days for the synthesis of nanoparticles (NPs). However, biogenic reduction of metal precursors to produce(More)
Part of Special Issue " Nonlinear and multiscale phenomena in space plasmas " Abstract. Observations from the Polar and FAST satellites have revealed a host of intriguing features of the auroral accelerations processes in the upward current region (UCR). These features include: (i) large-amplitude parallel (E ||) and perpendicular (E ⊥) fluctuating as well(More)
The present study attempts to characterize the traffic noise condition of a typical Indian city crossing. It uses a new methodology for characterization, giving importance to frequencies of sound primarily present in the noise. The characterization includes frequency-specific variation in the noise levels with time and location. The analysed data indicate(More)
A field experiment was conducted during rabi seasons of 2004–2005 and 2005–2006 at the Indian Agricultural Research Institute, New Delhi, to evaluate the effects of cropping systems and irrigation regimes on dry matter production, seed yield and economics of French bean. The treatments were comprised of five irrigation schedules (irrigation at critical(More)
The Caltech HIgh-speed Multi-color camERA (CHIMERA) is a new instrument that has been developed for use at the prime focus of the Hale 200-inch telescope. Simultaneous optical imaging in two bands is enabled by a dichroic beam splitter centered at 567 nm, with Sloan u and g bands available on the blue arm and Sloan r , i and z s bands available on the red(More)
Temperate and dry deciduous forest covers major portion of terrestrial ecosystem in India. The two forest types with different dominant tree species differ in litter quality and root exudates, thereby exerting species-specific impact on soil properties and microbial activity. This study aims to examine the influence of forest type or dominant tree species(More)
Indian mustard [Brassica juncea (L.) Czern & Coss.] is a long day plant, which requires fairly cool climatic condition during growth and development for obtaining better seed yield. Various workers have correlated crop growth and development with energy requirement parameters, such as growing degree days (GDD), photo-thermal unit (PTU), helios thermal unit(More)
