Herein, we found a "chimney effect" formed on the interface between the metal oxide and Nickel metal for the hydrogen evolution reaction, using density functional theory calculations and experimental methods. This special chemical environment around the interface leads the neighboring sites to be ...
In the study carried out, the calculations are made on the basis of the turbine pressure drop in the calculations made on the Manzanares pilot plant. For the pilot plant, the turbine pressure drop ratio is taken as 2/3. Power output (Po) calculation is made by following the following ...
The former reduces the evaluation to a few simple calculations and presents the relevant parameters and factors required in a number of Tables and graphs. The Brightside approach is almost entirely graphical using a series of curves and nomograms. Principal Design Parameters Chimney Height. For ...
Table 1. Comparison between the energy production costs of two x 200 MW solar chimneys and 400 MW coal and combined cycle power plants according to the present business managerial calculations [8]. Fig. 13 Energy production costs from solar chimneys, coal and combined cycle power plants depending...
A good level of agreement was achieved between the experimental data and numerical calculations. The comparison concerned both the mean and fluctuating dynamic features. Once validated, our model allowed the evaluation of the effect of different parameters on the heat and mass transfer features. These...
Given the narrow geometry of typical chimneys, 2D CFD calculations are considered adequate based on the assumption of uniform temperature distributions across the chimney width. The effect of the onset of turbulence is examined by comparing simulations performed with the laminar and a turbulent model ...
This paper studies the part of the chimney with shutters installed, and uses the fluid calculation software FLUENT to carry out numerical calculations. By simplifying the actual structure, the shutter flow field model is established. The exhaust temperature and infrared radiance of the ship's power...
The electronic and optical properties of the higher manganese silicides, known as the Nowotny "chimney-ladder" phases, are investigated by means of first-principles density-functional calculations and compared with the experimental results. According to our calculations, Mn 4 Si 7 is an intrinsic ...
(which is sufficiently accurate for small chimneys). The former reduces the evaluation to a few simple calculations and presents the relevant parameters and factors required in a number of Tables and graphs. The Brightside approach is almost entirely graphical using a series of curves and nomogram...
Natural convection experiments and numerical calculations performed without a chimney showed good agreement with the Le Fevre correlation for natural convection on a vertical plate. As the chimney height is increased, the heat transfer rates are enhanced for all Prandtl numbers, but the enhancement ...
