Which mechanism dictates Stirling engine efficiency at high cycling?

A)Heat exchanger ineffectiveness develops
B)Regenerator dead volume increases
C)Isothermal compression approaches ideal
D)Adiabatic expansion perfectly occurs

💡 Explanation

Increased transfer rate leads to inefficiencies because the heat exchangers' thermal resistance impairs complete heat transfer, driving losses during cooling and heating phases. Therefore, heat exchanger ineffectiveness rises due rather ideal conditions when properly controlled using Stirling cycle principles.
