This paper presents an effective quasi one-dimensional (1-D) computational simulation methodology and some important results for steady annular/stratified (or film wise) internal condensing flows of pure vapor. Though the approach is strictly valid for smooth, laminar vapor/laminar condensate flows, it is also approximately valid for laminar condensate and(More)
Reported experimental and computational results confirm that both the flow features and heat-transfer rates inside a condenser depend on the specification of inlet, wall, and exit conditions. The results show that the commonly occurring condensing flows' special sensitivity to changes in exit conditions (i.e., changes in exit pressure) arises from the ease(More)
Accurate steady and unsteady numerical solutions of the full 2-D governing equations – that model the forced film condensation flow of saturated vapor over a semi-infinite horizontal plate (the problem of Cess [1] and Koh [2])-are obtained over a range of flow parameters. The results presented here are used to better understand the limitations of the(More)
Preliminary work on the design of a low-cost linearly-polarized broadband PIFA operating in the UHF band (440 MHz) is presented. Extensive simulations using Ansoft HFSS are performed in order to model and optimize the antenna performance. High-density polystyrene foam is employed as a dielectric substrate/support for all antenna prototypes. The metal sheets(More)
We recently reported on a controlled deactivation/detoxification approach for obtaining cannabinoids with improved druggability. Our design incorporates a metabolically labile ester group at strategic positions within the THC structure. We have now synthesized a series of (-)-Δ(8)-THC analogues encompassing a carboxyester group within the 3-alkyl chain in(More)
