WebAn a-c voltmeter has been developed to indicate directly the percentage difference between an unknown voltage and the settings of the instrument dials. It is accurate to 0.05% from … WebMay 1, 1994 · Conclusions In the present study, the cyclic transient heat transfer within an injection mold are simulated using iterative DRBEM/FDM based on transient heat conduction model in a decoupled sequence. First, the transient mold temperature is computed using dual reciprocity boundary element technique.
