the paper aims at investigating the effects of chemical reaction and thermal radiation on the steady two-dimensional laminar flow of viscous incompressible electrically conducting micropolar fluid past a stretching surface embedded in a non-darcian porous medium. the radiative heat flux is assumed to follow rosseland approximation. the governing equations of momentum, angular momentum, energy, ...

A reaction calorimeter was used to study the rate and heat effects during CO2 absorption into aqueous solutions of N-methyldiethanolamine (MDEA). The experiments were carried out at constant pressure of 0.1 MPa and 0.3 MPa over a range of temperature from 293 K to 333 K. The amine content changed from 10 to 30 mass %. The experimental equipment and procedure were described with the emphasis on ...

UV cured epoxy systems represent complementary technology to the established heat cured epoxy systems for coating, adhesion and encapsulation of electronic devices. The UV cured epoxy systems offer significant benefits in terms of fast cure and thus very short production cycle time; low stress and better colour due to room temperature cure; process wise no mix ratio problem or anhydride handlin...

In this study, 4-mm-thick medium-density fiberboard (MDF) panels were heat-treated at 140 °C for 30 or 60 min and at 180 °C for 30 or 60 min. Then, 10-mm-thick lightweight honeycomb paperboards made from kraft paper (130 g/m, cell diameter of honeycomb, 14 mm; compression strength, 0.21 N/mm) were faced with the untreated and heat-treated MDF panels (thickness: 4 mm) using a two-component polyu...

The present numerical simulation is analyzed the Magnetohydrodynamic natural convection flow and heat transfer along a uniformly heated vertical wavy surface in presence of heat generation/absorption with temperature dependent variable viscosity. Using the appropriate transformations the governing boundary layer equations are reduced to non-dimensional forms. The resulting nonlinear system of p...

With the development of urbanization and population growth in the use of land for construction of residential and industrial areas and other infrastructure and turning to remove more vegetation,construction materials and non-systematic misuse of cities,urban areas have forced some changes that pollution and poor air quality,dehydration,high temperatures are some of its results.The temperature d...

load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...

The collisional effects on the kinetics of interactions between a high-power subpicosecond laser and a solidcarbon thin film in a fast-ignition scenario are investigated by one-dimensional particle-in-cell simulations. Collisions are found to play an essential role in energy absorption and transport, compared to collisionless cases. In the collisional cases, the absorption at the heating edge, ...

Solvents with an improved price/performance ratio allow for processes with less operating and/or capital expenditure. Therefore, from an industrial perspective, it is worth reviewing the R&D progress in designing new competitive solvents on a regular basis. This paper aims at discussing the potential of new solvent systems applicable as absorbents or entrainers for boosting the performance of a...

Nonlinear absorption has been detected and characterized by open aperture Z-scan in ionic liquids obtained by combination of 1-butyl-3-methyl-imidazolium cations with anions containing a transition metal (Zn) and thiocyanato groups. The laser source was a Ti:Sapphire oscillator (80-fs pulses, λ=810nm, repetition rate of 80.75MHz). This ionic liquid presents quite low heat capacity that favours ...
