The simulation follows the authors' experimental work on the effect of varying drying chamber roof inclination on the ventilation and drying processes, and their work on the development of simulation code to help optimise ventilation in such dryers.
In the first study, three residential areas were chosen in the Stockholm area with regard to a distribution of median income and through studying a solar map (showing possible annual insolation with respect to the position of the roof and the roof inclination).
The drying-chamber roof inclination and the chimney height are critical for the design in the geographical regions far from the equator, whereas the decisive parameters in the regions close to the equator are the drying chamber height and the area ratio of the dryer floor to chimney cross section.
The horizontal and PV roof tiles inclination annual irradiance in Sendai is 1222 and 1301 kWh/m2.
When integration is considered, it is often thought of as covering up the presence of the collector surfaces, hiding them behind the railings of flat surfaces, or putting them on top of inclined roofs with the same inclination as the roofs; hence, the final result is aesthetically inadequate.
Finally, the effect of roof solar chimney inclination angle on natural ventilation was studied in single room.
Their study included 3-D modeling of buildings using topographic maps, orthographic images, and large-scale city maps depicting roof type, area, inclination, and orientation, as acquired using light detection and ranging (LiDAR) technology.
It consists mainly of two methods, the first is advanced deep-hole blasting for the caving roof along the inclination of the face, which can reduce the distance from the weight of the roof and reduce the concentration of the weight.
British scholar Smart and Davies (1982) proposed a Roof Beam Tilt Theory, and its basic idea was to restrict the roof subsidence in entry from the coal side to the edge of gob side, he also put forward the standpoints that the inclination angle of roof and the rotation fulcrum position should act as two important parameters as to support design for retained entry.
This article studied the restrictive effect of geological and mining factors, such as lithological properties of roof strata, coal seam inclination, water source to bed separations, roof management method, dimensions of mining working face, and mining progress, on the formation of bed-separation water hazard.
It was found that as the angle of inclination of the roof increased, the mean static pressure on such roof has increased with an enlarged stagnation zone.
