1. Análise do processo de dessalinização solar com ênfase no método de umidificação e desumidificação
RESUMO A falta de água é um problema que afeta muitas regiões do nosso planeta, especialmente ilhas e locais de clima muito seco. Especialistas dizem que essa situação irá se agravar e que, em 2025, cerca de 1,8 bilhão de pessoas sofrerão com essa escassez. Embora métodos tradicionais de dessalinização sejam alternativas bem conhecidas e implantad

2. Mathematical Modeling And Numerical Simulation of Dropwise Condensation on an Inclined Circular Tube
ABSTRACT: Dropwise condensation can improve heat transfer process and, consequently, leads to considerable reduction in size and weight of condensers as well as improvement in the dehumidification process in many applications, especially in civil transport aircraft. It can also be used as an efficient cooling tool for electronics and electrical systems in ai

3. Rupture of glandular trichomes in Ocimum gratissimum leaves influences the content of essential oil during the drying method
Medicinal and aromatic plants are commonly sold dried; however, it is necessary to understand the effects different drying methods have on these materials, to ensure their efficiency and quality. Ocimum gratissimum L., Lamiaceae, is an aromatic plant whose essential oil is stored in glandular trichomes. This study aimed to confirm the effects of different dr

4. Analytical approach based on a mathematical model of an air dehumidification process
In this paper we developed an analytical solution for a mathematical model of an air dehumidification process. This solution has good accuracy when compared with reliable experimental data available in the literature. The present study was confined to the cases with the mass flow rate of desiccant solution being much greater than the minimum required by the

6. Desenvolvimento de um sistema de purificação de água com bomba de calor / Development of a water purification system with heat pump
The simplest process for water to reach adequate purity is the conventional distillation, however this method has drawbacks such as their high expense with electric energy and their high water consumption. Searching alternatives to produce purified water with saving energy and water cooling, but with production as purity as conventional, there is the possibi

7. Physicochemical characteristics and sensory profile of honey samples from stingless bees (Apidae: Meliponinae) submitted to a dehumidification process
Este estudo foi conduzido com o objetivo de avaliar o efeito do processo de desumidificação sobre as características físico-químicas e sensoriais do mel das abelhas sem ferrão. Amostras de méis de Melipona scutellaris e M. quadrifasciata foram submetidas ao processo de desumidificação, passando em seguida por avaliações físico-químicas (açúcar

8. Análise de trocadores de calor compactos para desumidificação de ar. / Analysis of compact heat exchanger for air dehumidification.
The objective of this work is to conduct a parametric analysis of the dehumidification process of compressed air in compact heat exchangers with Offset Strip Fins. The humidity carried by the compressed air should be removed from the system to prevent the condensation in the distribution lines and in the actuators or the final devices. The dehumidification p

9. An evaporative and desiccant cooling system for air conditioning in humid climates
Evaporative cooling operates using water and air as working fluids. It consists in water evaporation, through the passage of an air flow, thus decreasing the air temperature. This system has a great potential to provide thermal comfort in places where air humidity is low, being, however, less efficient where air humidity is high. A way to solve this problem

10. Analysis of the energy consumption and sensorial comparison for basil drying under different treatments. / Analise do consumo energetico e comparação sensorial para a secagem de manjericão sob diferentes tratamentos.
Several kind of air treatments are used to dry some products. Air, after some of these treatments, has higher temperatures than ambient temperatures and lower relative humidities, that results in lose of components responsible for color and flavor. This work has as goals the built and instrumentation of a plant to treat ambient air and a tray dryer. The prod
