Integrating phase change materials (PCM) into building envelopes has shown promises in reducing heat load and shifting peak energy demands. However, traditional passive (static) PCM systems have limitations, including inefficient use of latent missed opportunities for outdoor free cooling heating, as fixed thermal insulation between the environment restricts transition. In order to enhance utilization maximize heating interior comfort, this study introduces a dynamic strategy moving (DSMPCM)...
Abstract Despite its fundamental and practical relevance, flow structure evolution within volatile mixture drops remains largely unexplored. We study experimentally, using particle image velocimetry (PIV), the of internal during evaporation ethanol–water for different initial concentrations. The investigation revealed existence three stages in evolving behaviour these binary drops. propose an analysis nature focus on understanding successive as well transition from multiple vortices to a...
We propose a general theoretical expression for sessile droplets' evaporation, incorporating thermal effects related to the resistance of substrate and liquid properties. develop an which accounts associated with evaporative cooling; latter leads reduction in rate is not accounted current theories, i.e. ‘isothermal diffusion theories’. The threshold transition regime start be significant identified through dimensionless number includes properties as well kinetics evaporation. proposed theory...
Summary Numerical modeling of multiphase flow generally requires a special procedure at the solid wall in order to be consistent with Young's law for static contact angles. The standard approach lattice Boltzmann method, which consists imposing fictive densities sites, is shown deficient this task. Indeed, mass transfer along boundary could happen and potentially spoil numerical results. In particular, when angle less than 90 degrees, deficiencies model are major. Various videos that...
Forced convection experiments are challenging to perform in smooth horizontal circular tubes, because very low heat fluxes required ensure that the buoyancy effects do not enhance transfer coefficients. Previous work transitional flow regime mainly focused on mixed and limited has been conducted for forced transfer. It was therefore purpose of this study experimentally investigate pressure drop characteristics during specifically conditions. Vertical upward downward flows through a test...
Droplet coalescence is an important process in nature and various technologies (e.g. inkjet printing). Here, we unveil the surfactant mass-transport mechanism report on several major differences of surfactant-laden droplets as compared to pure water by means molecular dynamics simulation a coarse-grained model. Large scale changes bridge growth are identified, such lack multiple thermally excited precursors, attenuated collective excitations after contact, slowing down inertial regime due...
