摘要：

The present study examines the nature of dual solutions in hydromagnetic boundary layer flow a conducting fluid past an exponentially shrinking/stretching sheet with simultaneous thermal and concentration distributions in a porous medium. Due to the non-linearity of the model boundary value problem, both similarity transformation and the “MATLAB built-in bvp4c numerical scheme” are utilized to solve this problem. For shrinking surface flow, the model exhibits non-unique dual solutions and a linear stability analysis is executed in order to identify the stable and physically achievable solution. Influences of various emerging parameters on the flow with heat and mass transfer are discussed through graphs and in tabular form. A comparison has been made with existing results and excellent agreement is achieved. © 2022, The Author(s), under exclusive licence to Springer Nature India Private Limited.
