Due to sedimentation flow had been reduced in irrigation canal is well as threatening the blockage of water during low water flow Sediment trapping at different off-take angles depends on distribution of sediment at that angle of bifurcation. From this study we get the sediment distribution pattern at different off-take angles 30 O , 45 O , 60 O & 90 O , for different discharges Q1,Q2,Q3 . As discharge of main channel changes the behavior of sediment with respect to off-take angle also changes. The main purpose of this study is to minimize sediment trapping in open channel.60 O off-take angle gives more uniform flow which gives maximum off-take outlet discharge. At 60 O offtakes distribution of sediment is more as compared to other off-take angles. For 45 O off-take angle receives the maximum sediment trapping as compared to 30 O & 60 O off-take angle. We conclude that 60 O off-take angle is optimum angle for minimum sedime...

The compact heat exchanger and heat transfer devices performance can drastically improved by using microchannel arrays along with use of nanofluids. The parametric analysis of semicircular microchannel heat sink with distilled water and different concentrations of Multiwalled carbon nanotubes is carried out theoretically along with experimentation. The theoretical design is carried out for Minimum thermal resistance, maximum heat transfer coefficient, minimum friction factor and pressure drop along with minimum entropy generation. The microchannels with 200 μm hydraulic diameters are prototyped on accurate wire cut EDM. The effect of heat fluxes and Reynolds number is observed on heat transfer coefficient and pressure drop in laminar region. The performance of IC system is achieved best under Reynolds number 550 to 750. The heat transfer enhancement is observed 39 % over pure ...

CFD analysis will be performed using Ansys Fluent V14.5 using 2-D incompressible Reynolds Averaged Navier Stokes equations. A standard round air filter (Mahle KFA0247496) is used for performing experimental analysis with all laboratory equipment’s for calculating pressure drop(using differential pressure gauge) and studying velocity profile(using Dantec anemometer) and boundary conditions for 2Dimensional simulation air filter element are set with some approximations based on experimental values. Thus in order to improve air filtration efficiency parametric optimization of air filters is done by varying parameters like width of filter element, eccentricity of air flow in filter, and thickness of filter element using ANSYS Workbench after ...

The highest heat transfer coefficient is achieved by integration of micro areal channels along with nanofluids. In this research we have done theoretical calculations with experimental analysis of straight microchannel with circular section with distilled water and carbon nanotubes nanofluid. The geometrical parameters are optimized in theoretical investigations and experimental analysis is carried out. The Reynolds number which is function of mass flow and heater input wattage is varied to investigate effect on heat transfer coefficient. The Reynolds number is varied from 450-750. The nanofluids containing carbon nanotubes in concentrated solution are varied from 0.01 to 0.1 % of distilled water for experimental analysis and we get enhanced performance results with less pressure rise in this concentration of nanofluid. The nanofluids are prepared with two steps metho...
