Theoretical study of inherent irreversibility and thermal runaway of an exothermic reactive Eyring–Powell fluid flow through a saturated porous fixed horizontal channel with thermal radiation andvariable electrical conductivity is investigated. The reactive conducting fluid under bimolecular chem-ical rate law is propelled by pressure gradient. Ignoring the material assumptions, the governingdimensionless equations of the flow model are solved using semi discretization finite differencetechniques coupled with weighted residual method. The results in terms of flow rate, temperature,thermal runaway, Bejan number and entropy generation are presented in graphical form. From theresults, it is observed that parameter which argument the entropy production rate also enhances theBejannumber.Also,minimizationofentropygenerationisachievedatlowvaluesofthermalradiation,dissipation rate, electric field loading and viscosity variables.
