By analyzing and processing bountiful experimental data collected in short time , the curves of temperature variation of fast transient nucleate boiling are then drawn with wavelet analysis theory . also by setting up the mathematical model and applying the temperature variation curves to this mathematical model , heat flux density can be resolved 利用數(shù)學(xué)方法? ?小波理論成功分離了快速數(shù)據(jù)采集系統(tǒng)中溫度信號和噪音信號,得到瞬態(tài)沸騰的溫度變化曲線;并通過建立數(shù)學(xué)模型、利用實(shí)驗(yàn)所得的溫度變化曲線,求解出瞬態(tài)熱流密度。
