Not only in the Earth's mantle, in the atmosphere and in the outer layers of the Sun, but also in a chemical reactor, the exchange of heat may not be as effective as originally thought. There, because warm fluid rises and hence induces movement, the turbulent convection can be 100 billion times stronger than in the typical cooking pot. Hot fluids mix turbulently with warm fluids. As the temperature difference between the cold and warm sides increases, the heat transport increases...

By Tirabassi, Tiziano Buske, Daniela; Moreira, Davidson M; Vilhena, Marco T ABSTRACT A mathematical scheme is developed to simulate the vertical turbulent dispersion of air pollution that is absorbed or deposited to the ground. The scheme is an exact analytical solution of the atmospheric diffusion equation, without any restriction to the vertical profile of wind speed and eddy diffusivities, and taking into account the dry deposition by a boundary condition of a nonzero flux to the ground....

By Metzler, Roger D Blaschke, Marilyn W Prevent corrosion, emulsification and fouling by implementing these operational and chemical measures. In the production of petrochemicals, water is often used to control various chemical reactions or is a reaction byproduct. Because it is in intimate contact with the process streams, this water is commonly referred to as process water. Examples of processes that generate process water include ethylene, styrene and acrylonitrile production. In...
