TL;DR
This paper introduces two relativistic hydrodynamic codes, one for adiabatic flows with an approximate EOS and another for isothermal flows with a simple EOS, enhancing simulation capabilities.
Contribution
It presents novel numerical codes for relativistic hydrodynamics using simplified equations of state for both adiabatic and isothermal flows.
Findings
The adiabatic code uses an approximate EOS closely matching the perfect gas EOS.
The isothermal code employs a trivially simple EOS.
Both codes improve simulation efficiency and accuracy.
Abstract
The equation of state (EOS) is an important issue in numerical simulation codes for relativistic hydrodynamics. We describe a code for adiabatic flows, employing an EOS which is simple and yet approximates very closely the EOS of perfect gas in relativistic regime. We also describe a new code for isothermal flows, where the EoS is trivially given.
