“…For such a rapid heating of the element, heterogeneous nucleation is not thought as being a limiting process. Since for rapid heating conditions, the nucleation conditions are still related to classical Hsu criterion corresponding to rather low wall superheat [12]: a condition that is reached very early with our transient heating of the wall starting from saturation conditions. The visual observation confirms that vapor is formed over the wall.…”

“…The World Wildlife Fund (WWF) is working with partners to advance the science of water conservation (Roy et al, 2019). For this noble job, common people need to work with governments, businesses and communities to ensure that humans and freshwater species have sufficient water influx and that sustainable water use practices are promoted (Batista Mattos et al, 2019; Craig et al, 2019; Kossolapov et al, 2020). There can be several green investments for covering water shortages.…”

Despite the contributions of modern business practices to environmentally sustainable transformation, there is not enough information on different types of green technologies and their applications. Therefore, it is essential to identify and classify business models that focus on the management practices of green technology. While the literature on green technology business models has received increasing attention over the last decade, interdisciplinary research into this growing phenomenon is still in its infancy and fragmented. The study focuses on the need for green technology for water management worldwide. Such management practices for green technology represent a research gap in the study area because no one has worked in this field before. There should be research to address people's management practices of green entrepreneurial business. The literature highlights that the issue of water crises may be minimized with the management practices of green entrepreneurial business and by applying global green water treatment techniques. The authors believe that this study would be very beneficial for future research on policymaking based on management practices of green technology that promote environmental sustainability through a green business environment.

“…In the above-mentioned experiment, the microlayer beneath the nucleated bubble under atmospheric pressure or even lower pressure has been investigated. The pressure effects on microlayer dynamics have not been well investigated (2020, 2021) (Kossolapov et al, 2020;Kossolapov et al, 2021). During the actual reactor operation, the pressure reaches 15.5 MPa and it is difficult to carry out visual experiments at such high pressure.…”

High-speed laser interferometry is synchronized with a high-speed camera to visualize the dynamic microlayer behavior during bubble growth in a pool boiling under pressures from 0.1 to 0.3 MPa. An Indium–Tin-Oxide (ITO) film coated on sapphire is employed as the heating unit to provide the nominal surface heat fluxes in the range from 90 to 150 kW/m2. Based on the instantaneous microlayer thickness and photographed bubble images, microlayer formation and depletion and their relationship with bubble growth are analyzed. Appreciable effects of pressure on microlayer dynamics and bubble growth have been observed. At higher pressure, the microlayer existence time decreases and consequently, the contribution of the microlayer evaporation becomes less important. At elevated pressure, the effects of liquid subcooling and surface heat flux on bubble growth become more pronounced. The dimensionless instantaneous maximum microlayer thickness, δmax/√vt, shows exponential dependence on the ratio rd/rb,1 which increases linearly with time before the microlayer depletion. A correlation is proposed to predict the instantaneous maximum microlayer thickness synthesizing the two relations. The local heat flux will be overestimated and the wall temperature profile is contrary to the experimental observation when the flow inside the microlayer is negligible. During the bubble growth period, only part of the microlayer is evaporated and the internal flow inside cannot be neglected.
