Economical and efficient warming of pre-transfusion human blood has been a subject of extensive investigation. The objective of this study is to identify and analyze the effect of enhanced microwave warming of bank blood. The sample here has been assumed to be a 2D cylinder interacting with microwave irradiation. The mathematical interpretation for the study is performed by solving the equation of electromagnetic wave propagation along with the equation of energy balance and pertinent boundary conditions. The samples after being subjected to both lateral and radial irradiations of same intensity are investigated for the power absorption in the sample with respect to the sample size. The preliminary observations obtained are further analyzed and extended for spatial distribution scrutiny. The collaborative analysis of the spatial distributions of temperature and power in the human blood along with high heating rate and low thermal non-uniformity determine the optimal heating strategy. The observations at different sample sizes recommend radial irradiation as the optimal heating strategy for samples corresponding to OP: 1 and 3, and lateral irradiation for samples corresponding to OP: 2, respectively. Considering all the aspects, the present work recommends an efficient way for enhanced microwave assisted heating of body fluid samples (2D cylindrical geometry) with known or measurable dielectric properties.
