The effects of nebulization conditions on the size characteristics of the aqueous aerosol produced have been investigated for a cross-flow nebulizer. It is shown that the nebulizer gas flow rate does not affect the upper limit mean sizes of the aqueous droplets transported from the nebulization chamber but that the mean size of the analyte-containing aerosol itself is affected. Model equations are presented descriptive of the effects of gas flow rate and analyte concentrations on analyte aerosol size characteristics.

The study focused on the analysis of two neighboring zones in the Los Humeros geothermal field (LHGF), each one with different characteristic behaviors. A characterization methodology which can be used in geothermal reservoir engineering was designed and applied to study the zones. The static temperature profiles determined in wells located at the studied zone of the field ranged between 300°C and 360°C. From these temperatures, isotherms in the studied area were calculated and these trend to be deeper toward eastern zone of the field. Similarly the thicknesses tend to reduce in this direction. By analyzing the profiles of fluid circulation losses were determined during drilling of wells in this zone, the existence of low permeability in the rock formation was inferred. From the results of transient pressure tests, low permeability was confirmed. A marked difference in the productive characteristics between the wells, in the close neighborhood was also observed.  Behavior of wells also shows tendency to increase in their steam fractions, with the exploitation time. The characterization methodology applied to the studied zones, allows identify that there is a reservoir section with low permeability, but with high temperatures the depth increases.

Experimental and numerical consideration is given in the present work to an inline, inclined triple elliptic jet-group discharged in cross flow, a common configuration widely present in several domains, namely environmental, industrial and even medical. The experiments were described by particle image velocimetry and hot wire anemometry measurements, and the numerical simulation was based upon the finite volume method together with a non uniform grid system tightened close to the discharging nozzles. Generally, optimizing similar configurations is meant to reach optimum mixings in terms of heat and/or mass transfers. The present work will be particularly dedicated to the heat transfers generated within the examined multiple jet in cross flow configuration, for jets emitted under an injection height equivalent to , and under a variable injection ratio. After presenting the handled geometry, a validation of the numerical model is proposed. Afterward, a discussion of the reduced static temperature is presented. This is a highly interesting parameter due to its closeness, if not similarity under some circumstances, to the cooling efficiency.
