Influence of exhaust parameters on mid-infrared radiative characteristics of the plume北大核心CSCD

[Objectives] Infrared radiative (IR) characteristics of the plume are the main part of ship infrared radiation. The influence analysis of exhaust parameters on radiative characteristics is very important for developing ship stealth and anti-stealth technology. [Methods]In this work, the line-by-line method is applied to solve radiative transfer in gaseous media. Infrared radiative images of plumes under different temperatures and flow rates are obtained. Radiance, spectral radiative intensity, and spectrum-integrated radiative intensity over 3−5 µm are calculated and analyzed. [Results]Results show that there are obvious peaks of spectral radiative intensity curves at 4.18µm and 4.43 µm, and an obvious valley at 4.26 µm. [Conclusions] The infrared radiation characteristics of the ships exhaust plume are greatly affected by the exhaust temperature, but less affected by the exhaust flow rate. © 2023 The Author(s).

2 kHz high power smart transducer for acoustic sub-bottom profiling applications

In this study,a 2kHz Tonpilz projector was designed using a Terfenol-D and modeled in ATILA.For the purpose of modeling studies,it has been determined that a radiating head mass exhibits better transmitting current response（TCR） at 136 mm diameter,where the resonance occurs at 2.4kHz and the peak value of 118 dB re 1 μPa/A at 1 m occurs at 12 kHz.Also bolt at a 46mm distance from the center of the head mass offers resonance at 2.4kHz,and the peak value of 115.3 dB re 1 μPa/A at 1m occurs at 11.5kHz.This optimized design is fabricated and molded with polyurethane of 3mm thickness.The prototype was tested at the Acoustic Test Facility（ATF） of National Institute of Ocean Technology（NIOT） for its underwater performances.Based on the result,the fundamental resonance was determined to be 2.18kHz and the peak value of TCR of 182 dB re 1 μPa/A at 1m occurs at 14 kHz.The maximum value of the RS was found to be -190 dB re 1V/μPa at 1m at a frequency of 2.1kHz.     

Experimental observation and computer simulation on non-equilibrium grain-boundary segregation kinetics of phosphorus

An experimental study and computer simulation on non-equilibrium grain-boundary segregation kinetics and the critical time for phosphorus in 12Cr1MoV steel( which is used in steam pipeline of ships)are put forward in this paper. The segregation level of phosphorus with solution temperature 1050 ℃ at the isothermal holding temperature of 540 ℃ ,have been measured at grain-boundaries. A non-equilibrium grain-boundary segregation kinetics curve of phosphorus is given, The critical time for phosphorus non-equilibrium grain-boundary segregation is about 500 h at 540 ℃ for the experimental steel, When the holding time is longer than 1 500 h, non-equilibrium segregation disappears and the level of segregation reaches full equilibrium, The simulation using the kinetic equations of non-equilibrium grain-boundary segregation is in good accordance with the experimental observation for phosphorus in steel 12Cr1 MoV. The non-equilibrium grain-boundary segregation kinetic model is therefore proved.     

Numerical solutions for a two-dimensional airfoil undergoing unsteady motion

Continuous vorticity panels are used to model general unsteady inviscid, incompressible, and two-dimensional flows. The geometry of the airfoil is approximated by series of short straight segments having endpoints that lie on the actual surface. A piecewise linear, continuous distribution of vorticity over the airfoil surface is used to generate disturbance flow. The no-penetration condition is imposed at the midpoint of each segment and at discrete times. The wake is simulated by a system of point vortices, which move at local fluid velocity. At each time step, a new wake panel with uniform vorticity distribution is attached to the trailing edge, and the condition of constant circulation around the airfoil and wake is imposed. A new expression for Kutta condition is developed to study (i) the effect of thickness on the lift build-up of an impulsively started airfoil, (ii) the effects of reduced frequency and heave amplitude on the thrust production of flapping airfoils, and (iii) the vortex-airfoil interaction. This work presents some hydrodynamic results for tidalstream turbine.
