| 1 | Simultaneous effects of chemical reaction and Ohmic heating with heat and mass transfer over a stretching surface: A numerical study显示文摘In this article, we have considered the simultaneous influence of ohmic heating and chemical reaction on heat and mass transfer over a stretching sheet. The effects of applied magnetic field are also taken into consideration while the induced magnetic field is not considered due to very small magnetics Reynolds number. The governing flow problem comprises of momentum, continuity, thermal energy and concentration equation which are transformed into highly nonlinear coupled ordinary differential equations by means of similarity transforms, which are then, solved numerically with the help of Successive Linearization method(SLM) and Chebyshev Spectral collocation method. Numerical values of skin friction coefficient, local Nusselt number, and Sherwood number are also taken into account with the help of tables. The physical influence of the involved parameters of flow velocity, temperature and concentration distribution is discussed and demonstrated graphically. The numerical comparison is also presented with the existing published results and found that the present results are in excellent agreement which also confirms the validity of the present methodology. | S.R.Mishra M.M.Bhatti | 2017 | Chinese Journal of Chemical Engineering2017，25，9： | 2 |
| 2 | Free Convection of a Viscous Electrically Conducting Fluid Past a Stretching Surface显示文摘Free convection of a viscous electrically conducting liquid past a vertical stretching surface is investigated in the presence of a transverse magnetic field.Natural convection is driven by both thermal and solutal buoyancy.The original partial differential equations governing the problem are turned into a set of ordinary differential equations through a similar variables transformation.This alternate set of equations is solved through a Differential Transform Method(DTM)and the Pade approximation.The response of the considered physical system to the non-dimensional parameters accounting for the relative importance of different effects is assessed considering different situations. | Abdulmajeed D.Aldabesh P.K.Pattnaik S.Jena S.R.Mishra Mouna Ben Henda Iskander Tlili | 2022 | Fluid Dynamics & Materials Processing2022，18，2： | 0 |
| 3 | Chemical reaction effect of an axisymmetric flow over radially stretched sheet显示文摘A steady boundary layer flow over a porous flat plate has been considered in the present study.Mass transfer analysis with first order chemical reaction is also considered instead of heat transfer.The plate concentration is considered in the form of power law instead of taking constant.The goveming PDEs are transformed into ordinary differential equations using similarity transfomation and then these ODEs are solved by employing Runge-Kutta fourth order method associated with shooting technique.A parametric study of all involving parameters is obtained by the help of graphs.The major findings are:(i)the concentration of the fluid in its boundary layer decrease with increase in heavier species,the reaction rate parameter and the power law exponent;(ji)the rate of mass transfer increases with an increase in reaction rafe parameter and power-law exponent. | B.Nayak S.R.Mishra G.Gopi Krishna | 2019 | Propulsion and Power Research2019，8，1： | 0 |
| 4 | Synthesis, Electrical Conductivity, and Dielectric Behaviour of Polyaniline Doped with H2SO4;HCl and (HCl + NaNO2) Mixture显示文摘Acid doped Polyaniline(PANI)due to their increased electrical conductivity,are considered to be the most promising conducting filler materials.Hence,the present study,reports the synthesis of the PANI followed by acid doping,electrical conductivity and dielectric properties measurements of H2SO4;HCl and(Conc.HCl+NaNO2mixture)doped PANI.In order to know the effect of acetone washing on the electrical properties of acid doped PANI samples,the electrical properties of the non-acetone washed acid doped PANI samples are compared with that of their acetone washed counterparts.The PANI salt was prepared by conventional route using aniline hydrochloride and ammonium persulphate as an oxidant.PANI salt was subjected to 0.5M NaOH to form PANI base,which was further doped separately with H2SO4;HCl and(Conc.HCl+NaNO2mixture)respectively followed by acetone washing.A comparative electrical conductivity study between the acetone washed and unwashed PANI salt and H2SO4,HCl and Conc.HCl+NaNO2 mixture doped PANI were characterized by dielectric and impedance study. | J.Mohanty S.S.Mishra T.R.Das Mohapatra1 S.R.Mishra T.Badapanda | 2020 | Non-Metallic Material Science2020，2，2： | 0 |
| 5 | A numerical simulation for the control of radiative heat energy and thermophoretic effects on MHD micropolar fluid with heat source显示文摘The current paper explores the behavior of the thermal radiation on the time-independent flow of mi-cropolar fluid past a vertical stretching surface with the interaction of a transverse magnetic field.The ef-fect of thermo-diffusion(Soret)along with the heat source is incorporated to enhance the thermal prop-erties.Also,the convective solutal condition is considered that affects the mass transfer phenomenon.The transformed equations are modeled using suitable similarity transformation.However,the complex cou-pled equations are handled mathematically employing the Runge-Kutta-Felhberg method.The behavior of characterizing parameters on the flow phenomena as well as the engineering coefficients are displayed via graphs and the validation of the current outcome is reported with the previously published results in particular cases. | Ram Prakash Sharma S.R.Mishra | 2022 | Journal of Ocean Engineering and Science2022，7，1： | 0 |
