1. Effect of Pesticide Addition Sequence on the Preparation of Phytosanitary Spray Solutions
RESUMO: A adição de adjuvantes às caldas herbicidas visa preservar ou aumentar o efeito biológico do tratamento, porém é comumente realizada sem conhecimento das interações físico-químicas entre os produtos. Assim, objetivou-se neste trabalho avaliar os efeitos sobre a tensão superficial e o ângulo de contato decorrentes de diferentes sequências

2. Droplet dispersion angle measurements on a Pease-Antony Venturi scrubber
A Pease-Anthony Venturi scrubber is a gas cleaning device that uses liquid, injected in the equipment as jets, to remove contaminants from the gas. The liquid jet is atomized into droplets, which are dispersed throughout the equipment due to the turbulence. The performance of the scrubber is affected by the spatial distribution of the droplets. Although CFD

3. Combustion performance of an aluminum melting furnace operating with liquid fuel
The characteristics associated with the delivery of the fuel to be used as the energy source in any industrial combustion equipment are of extreme importance, as for example, in improving the performance of the combustion process and in the preservation of the equipment. A clean and efficient combustion may be achieved by carefully selecting the fuel and oxi

4. Nanoemulsões óleo de laranja/água preparadas em homogeneizador de alta pressão
The objective of this work was to use the high-pressure homogenizer (HPH) to prepare stable oil/water nanoemulsions presenting narrow particle size distribution. The dispersions were prepared using nonionic surfactants based on ethoxylated ether. The size and distribution of the droplets formed, along with their stability, were determined in a Zetasizer Nano

5. Projeto, construção e avaliação experimental de um lavador de gases industrial. / Design, fabrication and experimental evaluation of a industrial cyclone washer.
Ciclones são equipamentos largamente empregados na separação de partículas do ar ou na limpeza de gases de processos por ação da força centrífuga. Neste trabalho, um ciclone lavador modificado foi projetado, construído, e sua eficiência de coleta de partículas foi avaliada. O equipamento consiste de um ciclone separador tipo Americano com triplo c

6. Magnetic resonance imaging (MRI): a technique to study flow an microstructure of concentrated emulsions
Nuclear magnetic resonance (NMR) and magnetic resonance imaging (MRI) have recently been recognized as important techniques for R&D of products and processes, as is attested by several successful applications in different areas of chemical engineering in recent years. In this article we present new experimental methods based on MRI to study flow and microstr

7. Simulation of Airborne Microbial Droplet Transport
The framework for a simulation model which describes the dispersion of individual droplets of water containing viable microbes is presented. The model accounts for physical, chemical, biological, and measured meteorological parameters of each droplet at each of many short time steps. Repeating the modeling process for many droplets will simulate a cloud of d
