Modeling and Simulation Study of Flow and Temperature Characteristics of a Pen-shaped Plasma Torch
Abstract: This study presents the numerical modeling, simulation and experimental findings of plasma flow and temperature characteristics in pen-shaped plasma torch. The complex plasma flow characteristic due to the interaction between electric arc and nitrogen gas inside the pen-shaped plasma torch is modeled using the Maxwell’s and the Magnetic-Hydrodynamic (MHD) equations. Cartesian coordinate based finite volume discretization is used to solve numerically all the governing equations. At a specific boundary condition, …

TORCH Profile: A Convenient Method for Screening Infection in Pregnancy by ELISA: A Review
Abstract: TORCH is a medical acronym for a set of perinatal infections: toxoplasmosis, other (syphilis), rubella (German measles), cytomegalovirus (CMV), herpes simplex virus (HSV-1, 2). They are a group of viral, bacterial and protozoan infections that gain access to the fetal bloodstream transplacentally via the chorionic villi or hematogenous transmission any time during gestation or occasionally at the time of delivery via maternal-to-fetal transfusion. TORCH infections may result in abortion, still …

Parametric optimization of residual stress of TiO2 composite coating
Abstract: The primary objective was to develop a composite coating by utilizing the HVOF thermal spray technique and including TiO2. The substrate was covered with a high-quality composite layer utilizing the HVOF coating process. The TiO2-based powder and carbon powder were initially combined in the mixer for deposition. The composite powders were applied via an HVOF torch, namely the PT F4 model. The firearm frequently produces a high-speed flow of extremely …
