Enhancement of Solar Desalination Still Productivity Using Flash Evaporation (Dept.M)

Passive Vacuum Solar Flash Desalination

Study and Enhancement of Flash Evaporation Desalination Utilizing the Ocean Thermocline and Discharged heat

This paper reports on the results of experimental investigations of flash evaporation from superheated jet issues vertically upward from a round straight nozzle of 81.3 mm diameter. For the investigated range of jet superheat degree and velocity, it was shown that flash evaporation enhances with initial temperature increase. Due to the increase of jet inertia and subsequently the delay of jet s...

Improvement of Solar Still Productivity by Energy Absorbing Plates

A solar still is a viable option when the demand of potable water does not exceed more than 3 litres. Enhancement in distillate output from the solar still is a main goal of many researchers all over the world. In this research, the effect of copper and aluminium plates on distillate output is investigated experimentally as well as theoretically at different water depths under the same climate ...

Perovskite solar cells prepared by flash evaporation.

A simple vacuum deposition method for the preparation of high quality hybrid organic-inorganic methylammonium lead iodide perovskite thin films is reported. When sandwiched in between organic charge transporting layers, such films lead to solar cells with a power conversion efficiency of 12.2%.

A hybrid solar desalination system of air humidification dehumidification and water flashing evaporation Part I. A numerical investigation

This paper presents a hybrid solar desalination system consisting of a humidification dehumidification unit and single stage flashing evaporation unit. The hybrid solar desalination system was studied numerically. The heat and mass transfer and flow field is modeled theoretically in two-dimensional using finite difference scheme. For different operating and weather conditions the fresh water pr...
