- エントロピの代数解
比熱が一定と仮定するならば、エントロピの代数解を求めることができます。代数解は厳密ではありませんが、扱いやすく容易に近似解を得ることができます。
エントロピの関係式
初期値をs=0、T=T0、v=v0として(12.14)式を積分すると
また
初期値をs=0、T=T0、p=p0として(12.20)式を積分すると
また
初期値をs=0、v=v0、p=p0として(12.19)式を積分すると
が得られます。温度と圧力を変数としたエントロピの値は(13-2)式で計算できます。また、温度とエントロピを変数とした
圧力は(13-2)式を変形して
(13-4)式を変形すると
となり、圧力pは温度Tとエントロピsの関数となります。
- 空気の温度・圧力とエントロピの関係(代数解)計算結果
(1)代数解
表3-1から定圧比熱cp=0.2403(kcal/kg・deg)としてエントロピを計算します。温度t0=0℃、圧力p0=10000kp/m2におけ
るエントロピs0=0とします。
(13-2)式の計算結果を表13-1に示します。

代数解と数値積分の誤差グラフを図13-1に示します。
図13-1から温度が高くなるほど代数解と数値積分の誤差が大きくなることがわかります。
- 空気の温度・エントロピと圧力の関係(代数解)計算結果
(1)代数解
表3-1から定圧比熱cp=0.2403(kcal/kg・deg)としてエントロピを計算します。温度t0=0℃、圧力p0=10000kp/m2にお
けるエントロピs0=0とします。
(13-5)式の計算結果を表13-3に示します。

(3)代数解と数値積分の誤差グラフ
代数解と数値積分の誤差グラフを図13-3に示します。 ABS(代数解-数値積分
図13-3からエントロピが大きくなるほど代数解と数値積分の誤差が大きくなることがわかります。
