This study is a preliminary research to specify fire scenarios in storage tanks and evaluate the size based on type of fuel diameter tank by applying liquid evaporation model FDS . version 6.7.6 was used analysis, computational domains were established pool with same proportion. The results obtained from indicated that heat feedback surface relatively well matched previous empirical correlation...

In this paper, a circular intuitionistic fuzzy set is implicated, which the extension of and an set. The includes radius for both membership non-membership. After this, we describe TODIM method decision making, can handle quantitative qualitative criteria, as well imprecise uncertain information. takes into account decision-maker’s subjective preferences attitudes towards criteria while also co...

This paper reviews the stability, heat transfer efficiency and photothermal conversion optimization studies of solid-liquid phase change materials applied to water heaters. Suggestions prospects were proposed. The study shows that PCMs are mostly filled in tank, thermal storage devices or solar collector heater system with paraffin wax, addition can significantly improve performance. Further in...

The paper deals with the study of SISO and MIMO processes using PID controller for a coupled tank process. The PID controllers have found wide acceptance and applications in the industries. In spite of their simple structures, PID controllers are proven to be sufficient for many practical control problems. This paper presents the PID controller design for controlling liquid level of coupled tan...

In case of energy storage air conditioning system, due to load fluctuation, the traditional control methods can't obtain good effect, the model predictive control method can realize the optimization control system, and can overcome the influence of load fluctuation. In order to realize the predictive control, need to study model of air conditioning system. Ice storage air-conditioning system, b...

on the Columbia River plateau, a semiarid region in south-central Washington (Fig. 1), the Hanford Site At the Hanford Site, highly radioactive and chemically aggressive served as a plutonium production facility for nuclear waste fluids have leaked from underground storage tanks into the vadose zone. This paper addresses hydrogeological issues at the weapons from 1944 to the end of the Cold War...
