Experimental and numerical investigations with environmental impacts of affordable square pyramid solar still

A review: studying the effect of graphene nanoparticles on mechanical, physical and thermal properties of polylactic acid polymer

“…Since PLA is soluble in a variety of solvents such as tetrahydrofuran, chloroform, benzene and dioxane, PLA lm can be prepared by solution casting with any of these solvents. [76][77][78][79][80][81]…”

Thermal Desalination Systems: From Traditionality to Modernity and Development

“…As a result, numerous investigations focused on improving the performance of solar distillers. Consequently, the solar stills such as stepped type [53-55] (the absorber of the basin takes the steps shape), disk type [56] (the main effective absorber is a rotating disk), vertical type [57] (the distiller horizontal width is very small compared to its vertical height), tubular type [58-60] (the outer shape of the distiller is tubular/cylindrical), drum type [61, 62] (the absorber is a rotating drum inside the basin still), PV/T active type [63, 64] (distiller powered by PV panels), finned type [65] (the absorber of the distiller is a collection of fins), trays type [66-69] (the main effective absorber has trays to enlarge the surface area), inclined type [70] (the absorber is inclined), wick type [10, 71, 72] (the wick material is spread over the absorber of distiller), corrugated type [73,74] (the absorber of the distiller is a collection of corrugated shapes), spherical type [75] (the distiller takes the shape of sphere), double-effect type [76][77][78] (the distiller has two stages of water basins), multistage type [79] (the distiller has multistages of water basins), inverted absorber type [80] (the distiller has inverted absorber inside it), hemispherical type [81] (the distiller takes the shape of sphere), convex type [82,83] (the absorber has a convex shape), and pyramid type [84][85][86] (the distiller takes the form of pyramid) are found in the literature. In addition, numerous modifications were performed to improve the distiller performance.…”

Regenerative effect of pyramid solar still with incorporation of nickel oxide particles in the basin

“…The proposed system has produced distillate yield of 3.5 L/day with an efficiency of 50.85%. Al‐Madhhachi and Smaisim 20 have designed a square pyramid solar still and experimented in Alkufa climatic condition in Iraq. Thermal model has been developed and used to simulate the still in other locations.…”
