Performance evaluation of local clays from northern Nigeria for the refining of palm oil

  The effectiveness of adsorbents (unactivated and acid activated) developed from local raw materials - clay and diatomaceous earth samples - sourced from various geographical locations in northern Nigeria for use in the adsorptive bleaching of palm oil was studied. Two acids namely hydrochloric and sulphuric acids of varying strengths 20, 30 and 45% were used for the activation. A batch adsorption process of...

Study on effect of semi-angle between non-parallel walls on magneto hydro dynamic Jeffery Hamel flow using semi-analytical approach

  In this paper, magneto hydro dynamic (MHD) Jeffery-Hamel flow with nanoparticle has been investigated and its nonlinear ordinary differential equation has been solved through homotopy perturbation method (HPM). The governing boundary layer equations are written into a dimensionless form by similarity transformations. The effect of semi-angle has also been investigated in both convergent and divergent channel....
