    Inverse modeling of heat transfer with application to solidification and quenching
    (2002) Prabhu, K.N.; Ashish, A.A.
    The inverse modeling of heat transfer involves the estimation of boundary conditions from the knowledge of thermal history inside a heat conducting body. Inverse analysis is extremely useful in modeling of contact heat transfer at interfaces of engineering surface during materials processing. In the present work, the one-dimensional transient heat conduction equation was inversely modeled in both cartesian as well as cylindrical coordinates. The model is capable of estimating heat flux transients, chill surface temperature, and total heat flow from the source to the sink for an input of thermal history inside the sink. The methodology was adopted to solve boundary heat transfer problems inversely during solidification and quenching. The response of the inverse solution to measured sensor data was studied by carrying out numerical experiments involving the use of varying grid size and time steps, future temperatures, and regularization techniques.

    Image Acquisition and Electric Field Application in the Belousov-Zhabotinsky Reaction Using LabVIEW
    (Springer Science and Business Media Deutschland GmbH, 2024) Sibeesh, P.; Shajahan, T.K.
    This paper introduces LabVIEW-based software and hardware designed to simultaneously record and control chemical wave activity in the Belousov-Zhabotinsky (BZ) reaction. The chemical waves in the BZ reaction can be controlled by DC and polarized electrical stimuli. Our software can be used to study the interaction of DC or different types of polarized electric fields with chemical waves. The software allows the user to capture and save images for further analysis. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
