In order to accurately know the temperature field around a fixed anchorage and the heat loss of buried pipe we used the numerical simulation technology to simulate the temperature field in fixed anchorage of buried heating pipes, then, we got the intuitive temperature distribution figure and the size of heat loss. The simulation results indicate the necessity of effective insulation measures for fixed...
Steam pipelines play an important role in industrial enterprises. They joint the heat producer and users, and constitute the energy transmission networks. The total cost on steam pipelines include the expense of steel and heat insulator, converted expense of heat loss, and construction cost. This study develops a mathematical model of total cost on steam pipelines with golden section algorithm. The...
In this paper the design, fabrication methods and characterization of thin film meandered Pt resistive heater (size 20 ?? 20 mm2) with integrated Pt sensors on Si platform is presented. Pt heaters and temperature sensors were fabricated simultaneously by DC sputtering method. It was found that the fabrication process has significant influence on the electrical properties of the realized thin film...
A 60 liter capacity flat plate solar water heater has been designed and constructed with locally available material. The size is selected considering the daily requirement of a small family. In performance evaluation we have recorded water temperature of the solar water for consecutive hours during the mentioned sun shine period. During June-July period the maximum water temperature obtained was 71??C...
