摘要
介绍差示扫描量热仪(DSC)测量液体比热容的原理和方法,并测量4种不同体积分数的TiO2-BaCl2-H2O纳米流体比热容。结果表明,加入纳米粒子后其比热容都有所降低,并随TiO2体积分数的增大而逐渐减小。
Introduces the principle and usage of DSC(differential scanning calorimetry), measures specific heat of TiO2-BaCl2-H2O nano-fluids of four different volume fraction with NETZSCH DSC-200 PC Phox. The results show that specific heat of TiO2-BaCl2-H2O nanofluids is a little lower than that of BaCl2-H2O, and the specific heat is lower with the increase of volume fraction of TiO2.
