Aspen能否模拟超临界水？
Aspen能模拟超临界水吗？物性方法该如何选择？有相关的国内外文献可供参考吗？ 隐身猪 发表于 2015-12-22 20:25不能！
理由是啥呢。？？ STEAM-TAtemperature ：273.15 K to 1073 K.pressure ：1000 bar.
刚刚去模拟了一下，得出以下结果，不知道对不对，扔上图一张。

请问 这个是在哪修改啊？ tvb 发表于 2015-12-26 09:58

请问你用的什么物性方法呀？ IPWAS-95可以，你可以试一试 本帖最后由 banknation 于 2020-3-4 21:00 编辑
IAPWS-95
RangeThe IAPWS-95 formation covers a validityrange for temperatures from the melting line (lowest temperature 251.2 K at209.9 MPa) to 1273 K and pressures up to 1000 MPa.In this entire rangeof validity, it represents even the most accurate data to within theirexperimental uncertainty.In the stable fluid region, the IAPWS-95formulation can be extrapolated beyond the limits of validity listed above. The model behaves reasonably well when extrapolated to pressures up to2000 MPa and temperatures up to 3000 K as long as the conditions are in thefluid region (less than melting pressure at specified temperature, and greaterthan melting temperature at specified pressure).
