In this paper, heat and mass transfer in the unsteady squeezing flow between parallel plates is analyzed using a perturbation-iteration algorithm. The similarity transformation is used to transform the governing partial differential equations into ordinary differential equations, before being solved. The solutions of the velocity, temperature and concentration are derived and sketched to explai...

establishing satisfactory estimation methods of lake evaporation has been crucial vital for research and management of water resources and ecosystems. determining the accurate method to estimate evaporation from reservoirs in the investigation and management of water resources is very important. hence, in this study eight empirical methods such as; makkink, debruin-kejiman, penman, priestley-ta...

This study introduces an experimental and theoretical investigation of the performance of a proposed air dehumidification system using a nanofluid of γ-alumina nano-particles in LiBr/H2O as a desiccant. Comparative experiments organized using a central composite design were carried out to evaluate the effects of six numerical factors (air velocity, desiccant flow rate, air humidity ratio, desic...

This paper describes the theoretical and experimental investigations of the key components and also the performance analysis of a rotary wheel for using as a solid desiccant dehumidifier and also indirect evaporator cooling system. Solid desiccants have long been used in dehumidification and cooling systems for energy efficiency or reduce electricity. Although many mathematical models on th...

Nucleate pool boiling heat transfer coefficient have been experimentally measured on a horizontal rod heater for various liquid binary mixtures. Measurements are based on more than three hundred data points on a wide range of concentrations and heat fluxes. In this investigation, it has been confirmed that the heat transfer coefficient in boiling solutions are regularly less than those in p...

Gas control in coalmine was the critical issue since gas accidents give rise to a lot of harm. This paper put forward the optimization control strategy based on the turbulent mass transfer mechanism on the basis of previous research. First of all, gas turbulent mass transfer mathematical model was established in heading laneway. Three aspects were describing in detail, gas diffusion law and qua...
