J. Cent. South Univ. (2018) 25: 2883-2895 DOI: https://doi.org/10.1007/s11771-018-3960-z Analysis of influencing factors on suction capacity in seabed natural gas hydrate by cutter-suction...-suction flow, cutter-head rotating speed, cutting depth and suction port position on the cutter-suction capacity. The efficiency of the cutter-suction is analyzed based on the analysis of the variation......
J. Cent. South Univ. Technol. (2011) 18: 1272-1277 DOI: 10.1007/s11771-011-0832-1 Variation characteristics of aquifer parameters induced by groundwater source heat pump operation under variable... Abstract: The variation characteristics of aquifer parameters, induced by groundwater source heat pump (GWSHP) operation under variable flow, were theoretically analyzed through a case study, in which......
that SVM-Linear, SVM-RBF and BP models shared the similar ability to predict the heat capacity and power input with high accuracy. SVM-RBF demonstrated better stability for coefficient of performance...]. One of the main problems with the development of the HTHP is the choice of refrigerant. Additionally, heat capacity, power input and coefficient of performance (COP) are of great importance for a HTHP......
of pulsating heat pipe, when inclination decreased, thermal resistance became larger and heat transfer limit became lower. Heating power and cooling capacity need be matched with each other, and heat... of condenser (°C); is the mass flow of cooling water (kg/s); cp is the constant pressure specific heat of cooling water (J/(kg·°C)); is the outlet average temperature of cooling water (°C); is the inlet......

fabricated and tested from the bending angle, the bending position and the bending radius. The results show that temperature difference and thermal resistance increase while the heat transfer capacity... increasing, temperature became different between the evaporator and condenser, and the heat transfer capacity decreased. TAO et al [7] found that the heat transfer limit of axial grooved heat pipes after......
, thermal conductivity, specific heat, and wetting properties also have a significant effect on the quenching process [5]. The conventional quenchants have low thermal conductivities, which decrease... heat transfer mechanism. The properties of applied quenchants like thermal conductivity, heat capacity, viscosity, and density directly affect these heat transfer mechanisms [61-64]. Paraffin does......
