<jats:p>The present study investigates the hydromagnetic pulsating nanofluid flow in a porous channel with thermal radiation. In this work, we considered water as the base fluid and silver (<jats:italic>Ag</jats:italic>), copper (<jats:italic>Cu</jats:italic>), alumina (<jats:italic>Al</jats:italic>
<jats:sub>2</jats:sub>
<jats:italic>O</jats:italic>
<jats:sub>3</jats:sub>) and titanium dioxide (<jats:italic>TiO</jats:italic>
<jats:sub>2</jats:sub>) as nanoparticles. The Maxwell-Garnetts and Brinkman models are used to evaluate the effective thermal conductivity and viscosity of the nanofluid. The governing equations are solved analytically and the influence of various parameters on velocity, temperature and heat transfer rate has been discussed through graphical results. From the results, it is found that the rate of heat transfer enhances with an increase of nanoparticle volume fraction. Further, the heat transfer rate is higher for silver nanoparticles as compared with copper, alumina and titanium dioxide.</jats:p>
