Forced convector, which is one of the low temperature heating end users, not only high efficient but also conveniently adjustable, fits for low temperature metering heating system which can raise energy efficiency. So in this paper, in order to convenient for engineering application of forced convector, heat dissipation calculation method and heat dissipation characteristic equation are put forward...
During the process of the strip cooling after finished rolling, the mathematical model of hot rolled strip coiling temperature is very important for obtaining satisfactory microstructure performance and mechanical property of the hot strip. The outdated and the advanced mathematical models of coiling temperature are presented in the paper, and self-learning of online control strategy based on the...
This paper proposes a novel method for superheat and capacity control of refrigeration systems. The main idea is to control the superheat by the compressor speed and capacity by the refrigerant flow. A new low order nonlinear model of the evaporator is developed and used in a backstepping design of a nonlinear controller. The proposed method is validated by experimental results.
Cryoablation is a minimally invasive ablation technique for primary and metastatic hepatic tumors. Inadequate freezing around large blood vessels due to the warm blood flow can lead to local recurrence, and thus, necessitates close application of a cryoprobe to the large blood vessels. In this study, we constructed a perfusion model with an exvivo bovine liver and ablated the tissue around a large...
