The IP-LP Diff (Integer Programming - Linear Programming Difference) refers to the gap between the optimal solutions of an integer programming problem and its linear programming relaxation, where integer constraints are relaxed to continuous ones. LP Diff expansion typically involves analyzing how changes in the coefficients of a linear program can affect the optimal solution, often used to study the robustness of solutions or the sensitivity to perturbations. Both concepts are crucial in understanding the efficiency and performance of optimization algorithms in combinatorial problems.
HP Turbine is High Performance Turbine LP Turbine is Low Performance Turbine
Lp turbine diaphragm breaks due to positive pressure inside the condenser because of steam expansion.
my LP turbine differential expansion increase ,when rated gland steam temperature maintain.
Turbine diff expansion can be positive or negative and depends on the convention used. The usual convention is that positive expansion is rotor expanding faster (hotter) than fixed components. Expansion is dictated by steam flow, gland steam temperatures etc
It means Different songs in different regions . In diff places have diff folks .
Diff is short for difference.
In a low-pressure (LP) turbine, the rotor expansion is greater than the casing due to the design and operational conditions of the turbine. The rotor experiences a significant drop in pressure and temperature as steam expands through the turbine stages, resulting in a larger volumetric increase compared to the casing, which is designed to contain the steam flow with minimal expansion. This difference allows for efficient energy extraction from the steam, optimizing the turbine's performance while maintaining structural integrity in the casing. Overall, the rotor's greater expansion accommodates the dynamic changes in steam properties as it moves through the turbine system.
