A non-dimensional analysis of cardiovascular function and thermoregulation
… to form dimensionless quantities using the Buckingham Pi Theorem. Each dimensionless quantity, or parameter, is composed of definable physical quantities that reflect the interaction between various components of the system. From the analysis, a series of reference scales was identified and, …

Technology development targets for commercial In-Space Manufacturing
… of key system drivers on lifecycle cost. Then, Buckingham Pi theorem is used to identify nondimensional groups of input design variables, such as the ratio of areal density of launched components to that of ISM components, the ratio of ISM facility mass to that of ISM components, the ratio of …

Development, Evaluation and Improvement of Correlations for Interphase Friction in Gas-Liquid Vertical Upflow
… between the liquid and vapor phases. Using the Buckingham Pi Theorem, a dimensionless interphase friction force was tested and refined before being compared against seven other dimensionless parameters. Three correlations have been developed that establish a dimensionless interphase friction …

Heat transfer performance and prediction of low global warming potential R134a refrigerant alternatives
… system charge is critical. The condenser is typically responsible for 50% of the charge of a system; it is vital to have a fundamental understanding of the flow condensation heat transfer performance of low GWP refrigerants such as R513A and R450A. Flow condensation data were extracted from 35 …

Scaling a Prismatic Revolute Joint (Pr) Manipulator Using Similitude and Buckingham Pi Techniques
… polynomial. Scaling laws were developed from Buckingham's Pi theorem to facilitate the selection process of gearmotors. Nondimensional, nonlinear, differential equations were developed to describe viscous, Coulomb and static friction in comparative PM d.c. motors. From the insights gained …
