This study presents a novel investigation of using nanofluids to transfer thermal energy in an FPSC system. Using the governing equations in CFD simulations, the performance of an FPSC is studied numerically. The base fluid has been defined as a 60:40 blend of ethylene glycol and water. The effects of three distinct volume fractions of MXene nanofluids in the 0.01-0.1% range on the efficiency are investigated. The numerical findings revealed that employing MXene nanofluid increases outlet temperature efficiency by about 5.83%, 6.06%, and 6.31% when 0.01%, 0.05%, and 0.1% volume fractions of nanofluids are used, respectively. The research aims to create a validated numerical model that can be used to assess the effectiveness of FPSC utilizing ethylene glycol and water or other nanofluids of any mass fraction as a working fluid. To examine the overall effectiveness of the FPSC, a numerical model was created using Solidworks software and ANSYS ICEM CFD. The numerical findings revealed that (i) increasing the proportion of MXene nanofluid in the FPCS enhances efficiency to 0.1% volume fraction, and (ii) MXene nanoparticles may be used in the solar collector to improve efficiency.

The recycled cotton demand seems to be increased day by day: although the lower quality of the resulting items is the biggest barrier to cotton recycling. A thorough analysis of recycled cotton processes is therefore necessary from separation/shredding to completion. To that end, textile wastes made of pre-consumer cotton were systematically collected from the spinning mill. After pretreatment of cotton waste cellulose by caustic soda, alkali, and detergent in 100°C temperature for 30 minutes have produced white clean cotton. Following the next process by sodium hydroxide and isopropyl alcohol must produce Carboxymethyl Cellulose (CMC). CMC has big use in Textile printing, finishing, and warp sizing even in Ice-cream and food baking industry. Recent success stories will be addressed with the steady cotton processing to altering the properties of cell wall cotton and cotton fiber. The prospects of conduct...

The upward energy demand along with the depletion of conventional energy sources demands improved utilization of renewable energy resources. Among all renewable energy resources, solar energy is the most appropriate alternative to conventional energy sources owing to its inexhaustibility and green property. Solar collectors are devices that convert solar radiation into heat or energy. However, the efficiency of the solar collector is still not adequate. The competent step to enhance the efficiency of the solar collector is to use nanofluids. This study is carried out different phases viz. characterization and stabilization while both qualitative and quantitative methods used to evaluate the stability of nanofluids; several thermo-physical properties of Al 2 O 3 and CNC nanofluids such as thermal conductivity measured at four different temperature using KD2 Pro, viscosity and specific heat determined at similar temperature range by viscometer and differential scanning calorimetry respectively; implementation of nanofluids in the solar collector. The experiment is executed with a fixed flow rate and in steady-state conditions under open solar radiation. The experimental study has revealed that up to 2.48% and 8.46% efficiency of solar collector enhanced by using 0.5% Al 2 O 3 and 0.5% CNC nanofluids respectively. Moreover, nanofluids show good to moderate stability performance. In addition, the thermal conductivity of nanofluids increased while viscosity is in decreasing trend with increasing temperature. Applying nanofluids could enhance the efficiency of a flat-plate solar collector.

Aqueous ethylene glycol (60: 40; W: EG) used as base fluid and 0.1%, 0.3% and 0.5% volume concentrations were designated here. Crystal nanocellulose nanofluids were prepared by two-step method. Thermal conductivity, viscosity, density, specific heat capacity and pH were assessed with standard measurement method and equipment. In this present work, thermal conductivity of 0.3% CNC nanofluids was increased of about 25% at 80 0 c; viscosity decreased; 0.1% nanofluid exhibit lowest viscosity performance at 80 0 c. In addition to this, 0.5% CNC nanofluid performed better declination of specific heat with increasing temperature up to 70 0 C and lowest error percentage in density measurement. However, some data of the experiments were distracted.
