Experimental and numerical investigation of direct absorption solar collectors (DASCs) based on carbon black nanofluids
Wei, Shihao; Espedal, Lisbeth; Balakin, Boris; Kosinski, Pawel Jan (Journal article; Peer reviewed, 2024)Direct absorption solar collectors (DASCs) typically achieve high efficiency due to the volumetric heat absorption process facilitated by the working fluids. In this study, carbon black (CB) nanofluids were utilized as the ... -
Experimental study of hydrogen production using electrolyte nanofluids with a simulated light source
Wei, Shihao; Hikmati, Javad; Balakin, Boris; Kosinski, Pawel Jan (Journal article; Peer reviewed, 2022)In this research, we conducted water electrolysis experiments of a carbon black (CB) based sodium sulfate electrolyte using a Hoffman voltameter. The main objective was to investigate hydrogen production in such systems, ... -
Experiments and Models of Carbon Black-based Nanofluids for Photothermal and Electrical Applications
Wei, Shihao (Doctoral thesis, 2023-06-26)Nanofluid er en type væske som inneholder spredte nanopartikler, som kan forbedre deres termiske og elektriske egenskaper sammenlignet med basevæsker. Dette har ført til omfattende bruksområder, som for eksempel solenergilagring. ... -
Investigation of nanofluids in alkaline electrolytes: Stability, electrical properties, and hydrogen production
Wei, Shihao; Balakin, Boris; Kosinski, Pawel Jan (Journal article; Peer reviewed, 2023)Utilizing solar energy efficiently and manufacturing hydrogen economically are the primary goals in the energy industry. In this paper, we present a novel method to solve both issues by exploiting the electrolysis of ... -
Numerical investigation of direct absorption solar collectors based on carbon black nanofluids
Wei, Shihao; Balakin, Boris; Kosinski, Pawel Jan (Journal article; Peer reviewed, 2023)A novel model of a rectangular direct absorption solar collector (DASC) based on carbon black (CB) nanofluids for concentrated solar power is presented herein. Distributions of temperature, velocity, volume fraction of ...
