Simulation

A patented cycle for water desalination and power generation was evaluated with regard to thermal efficiency and water production. The inventor of the patent claimed that the patented cycle provides a thermal efficiency of 41%, which is higher than current combined water and power generation steam p

The successful development of a control system requires an appropriate definition of the control structure (i.e., selection of output, input and disturbance variables) and an efficient dynamical model on which the design, analysis and evaluation can be carried out. Thus, the confidence in the obtain

Solar drying, an energy-saving process, is an efficient food conservation solution for countries that often have only sun as an energy source. Decreased energy requirements for a drying and improved dewatering process result from lower moisture fraction. This investigation focuses on the study of wa

Desalination is a highly complex process, which requires an efficient and accurate control system in the plant to maintain operation at optimum conditions that result in energy savings and in preventing scale formation. A study of a multi-input multi-output (MIMO) control of mechanical vapour compre

This paper presents an experimental and theoretical study of a pad humidifier used in a new multi-stage solar desalination process in operation in Tunisia. The experimental operation of the humidifier is presented in terms of temperature, relative and absolute humidity, and the quantity of evaporate

A mathematical model has been developed to simulate the performance of an integrated extraction-stripping process based on the use of hollow fiber contactors. The model allows one to predict the time-dependent concentration profiles of the two phases involved in an individual extraction or stripping

Operation of an experimental RO plant connected directly to a wind system without energy storage was studied. The data obtained confirm the wide spectrum of operation of the plant with respect to the power available and the operation of the system. The development of an RO plant for variable charges

A thermodynamic simulation study was performed on the influence of greenhouse-related parameters on a desalination process that combines fresh water production using humidification–dehumidification with the growth of crops in a greenhouse. With the system under study, surface seawater trickles down

A computational model has been developed for the simulation and optimization of the pervaporation process. This model involves solving coupled mass and energy balances, and chemical potential equations using a genetic algorithm. A visual, windows-based, user-friendly design software has been develop

The morphology of a typical microfiltration membrane is a random, irregular, three-dimensional, and interconnected network. In this study, a realistic model of microporous membrane was obtained using Confocal Scanning Laser Microscopy (CSLM). CSLM allows accurate and non-destructive membrane section
