'Turbulence in Porous Media' introduces the reader to the characterisation of turbulent flow, heat and mass transfer in permeable media, including analytical data and a review of available experimental data. Such transport processes occurring a relatively high velocity in permeable media, are present in a number of engineering and natural flows. De Lemos has managed to compile, detail, compare and evaluate available methodologies for modelling simulating purposes, providing an essential tour for engineering students working within the field. - The hotly debated topic of heterogeneity and f

Guidelines for Quality Assurance of Installed Fine-Pore Aeration Equipment provides techniques and guidance for use in developing quality assurance requirements for specifying fine-pore aeration equipment. Three methods for specifying compliance testing are described, including information on appropriate applications, advantages and disadvantages of each method, and the procedures to be followed. Two methods are based on conducting oxygen transfer shop tests, and the third is based on conducting full-scale oxygen transfer testing. The basis for compliance testing includes oxygen transfer testing of selected individual diffusers or two reference tests-dynamic wet pressure and effective flux ratio. A description of test procedures and diffuser sampling is included. Quality assurance benefits all parties involved in the manufacturing, specification, and use of aeration equipment by providing quality diffusers delivered at the site at a reasonable cost.

Research into thermal convection in porous media has substantially increased during recent years due to its numerous practical applications. These problems have attracted the attention of industrialists, engineers and scientists from many very diversified disciplines, such as applied mathematics, chemical, civil, environmental, mechanical and nuclear engineering, geothermal physics and food science. Thus, there is a wealth of information now available on convective processes in porous media and it is therefore appropriate and timely to undertake a new critical evaluation of this contemporary i

Poroelasticity is a continuum theory for the analysis of a porous media consisting of an elastic matrix containing interconnected fluid-saturated pores. In physical terms the theory postulates that when a porous material is subjected to stress, the resulting matrix deformation leads to volumetric changes in the pores. This book is devoted to the analysis of fluid-saturated poroelastic beams, columns and plates made of materials for which diffusion in the longitudinal direction(s) is viable, while in the perpendicular direction(s) the flow can be considered negligible because of the micro-
