The present work represents a theoretical investigation of the performance of a solar air-heated desalination system using humidification-dehumidification (HDH) technique based on closed-water, open-air cycle under the geographical conditions of Dhahran (26.5°N, 50.2°E), Saudi Arabia. The HDH desalination system is suitable for small-scale decentralized fresh water production. It essentially co...

Work related to the first-principle modeling of a feedwater heater operating in a coal-fired power unit is presented, along with theoretical discussion concerning its structural simplifications, parameter estimation, and dynamical validation. The objectives of this work are as follows: (i) formulate and deploy a moderately complex first-principle model of a feedwater heater to reproduce operati...

magnetic force microscope ( mfm ) is a powerful technique for mapping the magnetic force gradient above the sample surface. herein, single-wall carbon nanotubes (swcnt) were used to fabricate mfm probe by dielectrophoresis method which is a reproducible and cost-effective technique. the effect of induced voltage on the deposition manner of carbon nanotubes (cnt) on the atomic force microscope (...

Introduction: Knowledge of the Moon's thermal structure is fundamental in understanding its origin and internal compositional variation, both of which are intertwined with the origin of the Earth and the rest of the solar system (NASA Strategic Goal 3C). The flow of heat that originates from the lunar interior can be measured, and serves as a constraint to the thermal structure. That is why hea...

Here we report polarization-sensitive, thermal radiation measurements of individual, antenna-like, thin film Platinum nanoheaters. These heaters confine the lateral extent of the heated area to dimensions smaller (or comparable) to the thermal emission wavelengths. For very narrow heater structures the polarization of the thermal radiation shows a very high extinction ratio as well as a dipolar...

Titan's near-surface atmosphere, with a relatively high density and weak ion production by cosmic rays or other sources, likely has lower electrical conductivity than the Earth's, possibly <1 fS/m. Direct measurements Relaxation Probe on Huygens constrain it to be <0.5 pS/m, extrapolation from higher altitudes suggests orders of magnitude this. We investigate why several published models indica...
