  • A computer real - time data acquisition device for the measurement of seebeck coefficients and electrical conductivities from 300k to 1000k were designed and installed in the present work . the numerical treatment of the measuring data was discussed also
    本項(xiàng)工作中,自行設(shè)計(jì)制作了一套用于測(cè)量300k 1000k范圍內(nèi)的seebeck系數(shù)和電導(dǎo)率計(jì)算機(jī)自動(dòng)測(cè)量裝置,并探討了測(cè)量數(shù)據(jù)的處理方法和過程。
  • Numerical simulation is a very important aspect for this research , in which the main task is to solve the system of radiation hydrodynamic equations , especially , we usually do this task using lagrangian coordinates , and in this case the numerical treatment of three - temperature energy equations is a main difficulty
    數(shù)值模擬是這項(xiàng)研究的非常重要的手段,其核心內(nèi)容是求解輻射流體力學(xué)方程組,而其中三溫能量方程的數(shù)值處理又是在lagrange坐標(biāo)下求解輻射流體力學(xué)方程組的主要難點(diǎn)之一。
  • Important missing aspects are : turbulent flow , numerical discretization techniques specially the relevant and difficult topic of numerical treatment of advection and related numerical methods of solution , variable property fluids , boundary layers , stability , etc . rather , it focuses on more primitive and fundamental issues of numerical treatment of advective equation and proper formulation of initial boundary value ( ib vp ) . numerical problems associated with advective dominated transport include spurious oscillation , numerical dispersion , peak clipping , and grid oriention . however , the key of numerical solution of three - dimensional advective problem is searching for a high - precision interpolating function , which can keep the computational stability and low damping
    3 、針對(duì)三維純對(duì)流方程提出了實(shí)用的擬協(xié)調(diào)單元模式,并與線性插值模式和協(xié)調(diào)單元模式比較后表明,在物理量大梯度變化的情況下,線性插值模式會(huì)產(chǎn)生較大的數(shù)值阻尼,導(dǎo)致解的失真;協(xié)調(diào)單元模式具有極高的計(jì)算精度和良好的計(jì)算穩(wěn)定性,還可較好地克服數(shù)值阻尼,但由于計(jì)及物理量的二階導(dǎo)數(shù)項(xiàng),計(jì)算工作量大,邊界條件給定尚存在一定的困難;而擬協(xié)調(diào)單元模式不僅具有協(xié)調(diào)單元模式計(jì)算精度高的優(yōu)點(diǎn),還避免了物理量的二階導(dǎo)數(shù)項(xiàng),可大大地減少計(jì)算工作量。
