A novel vapor-compression system concept employing carbon dioxide as the refrigerant is proposed to serve needs of a typical medium-size refrigerated truck used for multi-temperature (MT and LT) goods delivery. The design based on implementation an ejector only component increasing pressure from LT evaporation MT pressure, thus providing cooling effect at two different temperature levels with o...

An algorithm has been developed that retrieves water vapour profiles in the upper troposphere and lower stratosphere from optical depth spectra obtained by the Measurements of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation (MAESTRO) instrument onboard the SCISAT satellite as part of the Atmospheric Chemistry Experiment (ACE) mission. The retrieval relies on ro-v...

Abstract The article aims to present the methodology of estimating atmospheric water exchange components in lake. In absence direct precipitation and evaporation measurements, these balance elements need be estimated. However, inadequate selection estimation methods causes incorrect determination hydrological function lake effect it has on formation river drainage. Determination from lake’s sur...

Nonuniform evaporation from sessile droplets induces radial convection within the drop, which produces the well-known "coffee-ring" effect. The evaporation also induces a gradient in temperature and consequently a gradient in surface tension, generating a Marangoni flow. Here we investigate theoretically and experimentally the thermal Marangoni flow and establish criteria to gauge its influence...

The evaporation and the thermal accommodation coefficients for water in nitrogen were investigated by means of the analysis of evaporation of pure water droplet as a function of temperature. The droplet was levitated in an electrodynamic trap placed in a climatic chamber. The levitation time was in the range of seconds, which corresponds to the characteristic time scales of cloud droplet growth...

Nemo’s Garden® Project aims at creating a green, alternative, and original agriculture system based on underwater greenhouses (biospheres) developed for areas where plant growth is difficult in the terrestrial environment due to climate conditions new global warming issues. Experiments were designed performed measure thermal hygrometric behaviour inside biosphere; simple theoretical model was a...

The law of conservation of linear momentum is applied to surface gas exchanges, employing scale analysis to diagnose the vertical velocity (w) in the boundary layer. Net upward momentum in the surface layer is forced by evaporation (E) and defines non-zero vertical motion, with a magnitude defined by the ratio of E to the air density, as w = E ρ . This is true even right down at the surface whe...

direct contact membrane distillation (dcmd) which emerges as an alternative separation technology can effectively perform a colloidal separation process under thermal driven force. dcmd is capable of extracting pure water from aqueous solutions containing non-volatile nanoparticles through the hydrophobic microporous membrane when a vapour pressure difference was established across the membrane...
