“…Polydimethylsiloxane, polyethylene terephthalate and rubber are some typical polymers used to develop flexible sensor. [23][24][25] Recently, numerous types of such mechanisms have been proposed by using carbon-based substances combined with flexible and stretchable polymers. Fabric and carbon-based electronics for the recognition of human health and motion controlling are highly advantageous because of their great flexibility and stretchability properties.…”

Recently, new developments in the design and performance optimization of smart mechanisms associated with natural and man-made hazards have progressed considerably. This is mainly owing to advances in smart sensing mechanisms including communication and data technologies. This work provides a detailed overview of existing improvements on smart hazard monitoring equipment and materials applied in textile sensing systems. Given that fire is one of the most common disasters in many countries such as Australia, and every year many firefighters are affected by these unfortunate incidents, the focus of this study is on firefighters' protective clothing Fire Fighter Protective clothing. This review provides a unique opportunity to study smart sensing systems in coating technologies, potentially provides more effective techniques for training and better safety protocols of fire fighters. It aims to revisit the existing advances and address recent challenges and opportunities for improvement in the domain of smart coating and fire protective wearables. The goal of this review is to provide information about smart coating in protective clothing for firefighters. The capability of some of these clothing in managing thermal stresses, responding to humid environment, monitoring some critical parameters and adapting to the size of the wearers (clothes fabricated with phase change and shape memory substances) made them attractive choice in adjusting specific design features of industrial textiles. Various types of phase change and shape memory substances are defined and a combination of these substances within the structure of fabrics are presented. This paper also provides a detailed review on the heat exposure and capability of the shape memory substances (SMM) and phase change materials (PCM) to delay the heat transfer through fire fighter protective clothing. Referring to the former research, several issues have been detected using such substances. For instance, combination of phase change and shape memory materials needs fundamental improvements with regards to assessment techniques and testing criteria. Additionally, recent improvements in the domain of PCM and SMM including modifying mechanical features, functionality, and durability under different conditions have been informed. It has been suggested that the major problem in developing fabric-Phase Change Materials (PCMs) and Shape memory material (SMM) systems is their usage methods. At last recent developments on wearable monitoring systems applied in the firefighters’ protective gear. Wearable sensors are usually used directly on the body or located on wearable items to monitor information related to firefighters’ safety.

Current work presents the application innovative shape of twisted tape including barriers and holes. This disturber device has been installed inside the absorber tube of solar system and such barriers helps to increment of swirl flow and appearance of holes decrease the resistance of fluid flow. Turbulent regime has been presumed for current usage and finite volume technique has been developed for this problem. Involving the hybrid nanoparticles within the water makes the properties of nanomaterial to increase and correlations based of experimental outputs were applied for predicting the features of carrier fluid. Impacts of height of barrier and number of revolution as well as inlet velocity has been depicted in outputs with considering constant value of heat flux over the top surface. Besides, variable heat flux effect has been utilized to show the behavior of system at various time stages of the day. Involving longer barrier makes the swirl flow to rise and temperature of outer wall decreases. As revolution of disturber tape elevates, the residence time grows and stronger secondary flow can be generated.

“…Their observations indicated that adding the silica-alumina nanopowders has a considerable capability for increasing the heat storage features of the NaNO 3 -KNO 3 binary salt. Numerical approaches were developed for complex systems [61][62][63][64][65][66][67][68][69][70][71]. Phenomenons for changing the phase of paraffin were examined by Lacroix and Benmadda [72] with involving various factors such as size of fin and hot side temperature.…”

With the involvement of sinusoidal containers of phase change material (PCM) inside the duct, new configuration for the ventilation system has been achieved in the current paper. Mixture of TiO2 and RT25 was assumed as PCM, and the temperature of domain is fixed at 25°C at the start of the process. Owing to the radiation of the sun, air becomes warmer up to 35°C and with entering the air into the domain with Re = 6000, the melting process starts. The cold air at the outlet section can be utilized for ventilating the room. Homogeneous model for NEPCM and K‐ɛ approach for turbulent air flow has been incorporated. ANSYS FLUENT was applied for simulating this unsteady mechanism, and verification of the model was done according to previous experimental work. To control the air gap among tanks, the factor “b” was utilized and the influence of the fraction of titanium oxide (ϕ) was analyzed in results. As nano‐sized material has been added, more heat can be received to RT25 and the completed process can be reached in lower time. With considering the highest “b,” as nano‐sized material, the required time reduces from 20,672 to 19705 s. When ϕ = 0, growth of b leads to a reduction of time of about 42.57%.
