Laminar free and forced convection cooling of a semi permeable open cavity
Heat transfer inside a semi porous two-dimensional rectangular open cavity was numerically investigated. The open cavity comprises two vertical walls closed to the bottom by an adiabatic horizontal wall. One vertical wall is a porous and an inflow of fluid occurs normal to it. The other wall transfers a uniform heat flux to the cavity. It shows how natural convection effects may enhance the forced convection inside the...

Safety analysis on hazardous chemicals transportation by Indian roads
In engineering industries, necessary safety measures during manufacturing, storage and loading of the chemicals which are dangerous in nature, also known as hazardous chemicals are generally taken. There are means to monitor and control the same, but once the product vehicle is loaded and leaves the plant premises, there is hardly any control over it. The safety of it largely depends on the condition of vehicles and the...

Growth pattern of two crop species on bio-remediated hydrocarbon polluted soils
The effectiveness of agricultural wastes as bioremediation materials is gaining research attention as a better option in mitigating the issue of crude oil effects in soil environment. In the present study, the growth performance of Telfairia occidentalis and Arachis hypogaea linn in crude oil polluted soil amended with plantain peels (PP) and cocoa pod husks (CPH) were investigated. Eight kilograms (8 kg) each of dried...

Effect of the aging process on mechanical properties and machinability in AA6013 aluminum alloys
This study investigated the effects of aging process on the mechanical properties and machinability in AA6013 aluminum alloy. To this end, AA6013 aluminum alloy samples were maintained in heat treatment furnace at 530°C (for 8 h) and placed in hot water (at 70°C), and then subjected to aging process by storing in heat treatment furnace (at 180°C) for various times (1, 3, 6, 9, 12 and 24 h). Changes in...

Assessment of non-ionizing radiation from radio frequency energy emitters in the urban area of Natal City, Brazil
The massive increase of wireless communications in the world calls for responsible actions by governments in order to prevent possible health hazards. In addition to cellular towers overcrowding in urban areas, it is also important to consider other radio frequency radiations from different sources. The electric field intensity is one of the fundamental parameters to assess the exposure of human beings to Non-Ionizing...
