The objective of this project is to study examines the problem of peristaltic flow in a tube with an endoscope subjected to rotation. The effect of an endoscope and rotation of the peristaltic flow of a Jeffrey fluid through the cylindrical cavity between concentric tubes is investigated. The analytical expressions for the pressure gradient, velocity, pressure rise, friction force on the inner ...

• Dynamics of driven ATR characterised experimentally and numerically. Optical acoustic methods agree well with LBM numerical model. Mixing regime depends strongly on applied amplitude, a , agitation frequency, f . power number increases re as 2 3 above critical value. Agitator tube induces fluid wakes, motion closely coupled to velocity field. This study investigates the dynamics novel, oscill...

One of the effective methods for energy conservation and emission reduction in coal mines is to utilize waste heat recovery technology recover mine return air heat. The gravity pipe widely used due its sustainable economic advantages, but transfer a complex process influenced by multiple parameters. A single-tube resistance model calculation based on enthalpy difference were established exchang...

In this work, the mathematical modelling of peristaltic transport for incompressible Sutterby fluid through cavity between coaxial tubes where inner tube is fixed and outer has sinusoidal rhythmic fluctuations along channel’s walls presented. Under assumption long wavelength low Reynolds number, governing equations (motion, temperature, concentration) are illustrated in cylindrical coordinates....

In the present study, the effective parameters of water-Al2O3 nanofluid flowing in flat tubes are investigated using the EFAST Sensitivity Analysis (SA) method. The SA is performed using GMDH type artificial neural networks (ANN) which are based on validated numerical data of two phase modeling of nanofluid flow in flat tubes. There are five design variables namely: tube flattening (H), flow ra...

Recently, there have been a lot of earthquakes in Japan. It is necessary to promote seismic isolation devices for buildings. The devices have been hardly diffused in attached houses, because the devices are very expensive. We should develop a low-cost seismic isolation device for detached houses. We suggested a new seismic isolation device which uses a two-layer circular tube as a unit. If hyst...

Abstract In the present work, operation characteristics of a disk-type rotating detonation engine (DRDE) with constant chamber area were experimentally studied for various total mass flow rates and wide variety equivalence ratios hydrogen–air mixtures. From direct visualizations, wave was found to propagate near outer wall combustion chamber, regardless mode. For test conditions, single- double...

Abstract   An empirical investigation was carried out to study convective heat transfer of nanofluid flow inside an inclined copper tube under uniform heat flux condition. Required data are acquired for laminar and hydrodynamically fully developed flow inside round tube. The stable CuO-base oil nanofluid with different nanoparticle weight fractions of 0.5%, 1% and 2% was produced by means of ul...
