Developed during a DRDO Internship
LOW-Q
Cryogenic Package Thermal Analysis Tool
A web-based engineering platform developed to perform steady-state and transient thermal analysis of cryogenic packages, enabling evaluation of conductive and radiative heat transfer, thermal mass, cooldown behaviour, and cryocooler compatibility.

What is LOW-Q
A focused thermal analysis workflow for cryogenic package studies.
LOW-Q connects material data, heat-transfer equations, cryocooler selection, and visualization into a single engineering tool.Solution
LOW-Q brings the calculations into one workflow.
The platform automates thermal-property lookup, heat-transfer calculations, cooldown estimates, and result plotting.Capabilities
Steady-state and transient analysis modules.
Conduction, radiation, thermal mass, cooldown, Qdot, thermal profiles, and cryocooler analysis.Applications
Designed for cryogenic engineering studies.
Detector packages, space instrumentation, vacuum insulated systems, and scientific research hardware.Analysis Modules
Open each calculation workspace from a single entry point.
Module pages are connected to the LOW-Q backend calculations and visualization outputs.Conduction
